iotests: 211: Remove duplication with VM.blockdev_create()

The blockdev_create() function in this test case adds an error check
that skips the test in case of failure because of memory shortage, but
provides otherwise the same functionality as VM.blockdev_create() from
iotests.py. Make it a thin wrapper around the iotests.py function.
