Peter Wang 93e6c0e19d scsi: ufs: core: Clear cmd if abort succeeds in MCQ mode 
In MCQ mode, if cmd is pending in device and abort succeeds, response will
not be returned by device. So we need clear the cmd, otherwise timeout will
happen and next time we use same tag we will get a WARN_ON(lrbp->cmd).

Below is error log:

  <3>[ 2277.447611][T21376] ufshcd-mtk 112b0000.ufshci: ufshcd_try_to_abort_task: cmd pending in the device. tag = 7
  <3>[ 2277.476954][T21376] ufshcd-mtk 112b0000.ufshci: Aborting tag 7 / CDB 0x2a succeeded
