In MCQ mode, the case where OCS is updated to aborted is as follows
1. when abort processing is completed
2. When a duplicate command occurs
In case of 1 situation, cmd should be re-request.
So in the case of cmd whose abort processing is completed in MCQ mode,
the ufs driver needs to update to scsi with DID_REQUEUE.
v1->v2: change the method of determinging mcq and legacy mode.
check cqe value for checking mcq mode
