block: fix module reference leakage from bdev_open_by_dev error path
At the time bdev_may_open() is called, module reference is grabbed
already, hence module reference should be released if bdev_may_open()
failed.
This problem is found by code review.
Fixes: ed5cc702d311 ("block: Add config option to not allow writing to mounted devices")
