From: Eric Biggers <ebiggers@xxxxxxxxxx> Fix ufshcd_print_trs() to consider UFSHCD_QUIRK_PRDT_BYTE_GRAN when using utp_transfer_req_desc::prd_table_length, so that it doesn't treat the number of bytes as the number of entries. Originally from Kiwoong Kim (https://lkml.kernel.org/r/20200218233115.8185-1-kwmad.kim@xxxxxxxxxxx).
