[PATCH v3 1/3] blktests: nvme/{033-037,039}: skip passthru tests on multipath devices

[Martin Wilck <martin.wilck@xxxxxxxx>]

NVMe multipath devices have no associated character device that
can be used for NVMe passtrhu. Skip them.

Signed-off-by: Martin Wilck <mwilck@xxxxxxxx>

v3: improve patch subject (Shinichiro Kawasaki)
v2: used more expressive function name for non-multipath test (Daniel Wagner)
