null_blk: Fix missing mutex_destroy() at module removal
[ Upstream commit 07d1b99825f40f9c0d93e6b99d79a08d0717bac1 ]
When a mutex lock is not used any more, the function mutex_destroy
should be called to mark the mutex lock uninitialized.
Fixes: f2298c0403b0 ("null_blk: multi queue aware block test driver")
