scsi: ufs: core: Support dumping CQ entry in MCQ Mode

Browse Source 
Enhance the ufshcd_print_tr() function to support dumping completion
queue (CQ) entries in MCQ mode when an error occurs.  This addition
provides more detailed debugging information by including the CQ entry
data in the error logs, aiding in the diagnosis of issues in MCQ mode.
