Scsi: ufs: fix issue of task tag in used 



Fix a coding error that lrb_in_use bitmap is cleared twice after its
corresponding request is completed. Otherwise, a tag, which is assigned
to a new request, get released from lrb_in_use in the first clear shall
be cleared again even before the new request is actually completed. Fix
this error by removing the second clear.
