nvme/039: avoid module loads for various transport types

The test case nvme/039 does not depend on nvme transport type and does
not require modules for the transport types. The _nvme_requires call in
requires() loads the modules and those modules are left unloaded after
the test case run. This causes failures of following nvmeof-mp test runs
with message:

  modprobe: FATAL: Module nvmet is in use.

To avoid the unnecessary module loads, remove _nvme_requires call.
Instead, just check existence of nvme command.
