6.12-stable review patch. If anyone has any objections, please let me know.

commit f103396ae31851d00b561ff9f8a32a441953ff8b upstream.
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.
