block/017: extend IO inflight duration
The test case block/017 often fails on slow test systems. When it runs
on QEMU and kernel with LOCKDEP, it fails around 50% by chance with
error message as follows:
The test case issues one read and one write to a null_blk device, and
checks that inflight counters reports correct numbers of inflight IOs.
To keep IOs inflight during test, it prepares null_blk device with
completion_nsec parameter 0.5 second. However, when test system is slow,
inflight counter check takes long time and the read completes before the
check. Hence the failure.
To avoid the failure, extend the inflight duration of IOs. Prepare a
null_blk device without completion_nsec parameter and measure time to
check the inflight counters. Prepare null_blk device again specifying
completion_nsec parameter 0.5 seconds plus the measured time of inflight
counter check.

However, it was not a good solution and _have_driver() was modified

check,common/rc: load module in _have_driver() and unload after test
The commit 06a0ba866d90 ("common/rc: avoid module load in
_have_driver()") removed module load from _have_driver(). However, it
was pointed out no module load in _have_driver() is confusing and adds
complexity [1]. It requires explicit module loads and unloads in number
of test cases. The module unloads must be checked if unload is safe or
not. Also module load error must be handled. To avoid these complexity,
a new helper function would be required, but it will be look like the
_have_driver() with module load.
Then revert back the feature to load module in _have_driver(). To
address the issue that the commit 06a0ba866d90 tried to fix, record the
modules loaded by _have_driver() in MODULES_TO_UNLOAD array. Unload
the recorded modules after each test case processing completed. This
avoids the side-effect by the modules loaded by _have_driver().

The commit e9645877fbf0 ("common: add a helper if a driver is

driver or module is available no matter whether it is a loadable module
or built-in module. It was assumed that _have_modules() whould check
that specified modules are loadable and not built-in.
However, the function _have_modules() returns true even if the specified
modules are built-in and not loadable. This causes failures of some test
cases on test system with built-in modules such as nbd/004. It also
means that _have_modules() and _have_driver() have same functionality.
To avoid the unexpected failures, fix _have_modules() to return false

exists by searching the module file path. If the module file does not
exist, return false. Also add comments to describe the difference
