scsi: ufs: core: Update compl_time_stamp_local_clock after completing a cqe

lrbp->compl_time_stamp_local_clock is set to zero after sending a sqe
but it is not updated after completing a cqe.  Thus the printed
information in ufshcd_print_tr() will always be zero.

Update lrbp->cmpl_time_stamp_local_clock after completing a cqe.

Log sample:

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