[PATCH blktests v2 11/18] nvme/rc: do not cleanup external managed loop device

[Daniel Wagner <dwagner@suse.de>]

If the test setups a loop device itself (not created by
_nvmet_target_setup), _nvmet_target_cleanup should not cleanup the block
device automatically.

Because _nvmet_target_cleanup has no way to figure this out by itself if
it is managed or not, the caller needs to pass in the block device type.
