[PATCH v2] scsi:ufs:core: update compl_time_stamp_local_clock after complete a cqe

[liuderong]

From: liuderong <liuderong@xxxxxxxx>

For now, lrbp->compl_time_stamp_local_clock is set to zero
after send a sqe, but it is not updated after complete a cqe,
the printed information in ufshcd_print_tr will always be zero.
So update lrbp->cmpl_time_stamp_local_clock after complete a cqe.

Log sample:
ufshcd-qcom 1d84000.ufshc: UPIU[8] - issue time 8750227249 us
ufshcd-qcom 1d84000.ufshc: UPIU[8] - complete time 0 us
