scsi: ufs: remove "errors" word in ufshcd_print_err_hist()

Remove "errors" word in output string by ufshcd_print_err_hist() since not
all printed targets are "errors". Sometimes they are just "events".

In addition, all events which can be treated as "errors" already have "err"
or "fail" words in their names.
