Can Guo 8bb2dde069 scsi: ufs: Properly release resources if a task is aborted successfully
In current UFS task abort hook, namely ufshcd_abort(), if one task is
aborted successfully, clk_gating.active_reqs held by this task is not
decreased, which makes clk_gating.active_reqs stay above zero forever, thus
clock gating would never happen. Instead of releasing resources of one task
"manually", use the existing func __ufshcd_transfer_req_compl().  This
change also eliminates a possible race of scsi_dma_unmap() from the real
completion in IRQ handler path.
