scsi: trace: Show rtn in string for scsi_dispatch_cmd_error()
By default the scsi_dispatch_cmd_error() return value is displayed in
decimal:
kworker/3:1H-183 [003] .... 51.035474: scsi_dispatch_cmd_error: host_no=0 channel=0 id=0 lun=4 data_sgl=1 prot_sgl=0 prot_op=SCSI_PROT_NORMAL cmnd=(READ_10 lba=3907214 txlen=1 protect=0 raw=28 00 00 3b 9e 8e 00 00 01 00) rtn=4181
However, these numbers are not particularly helpful wrt. debugging
errors. Especially since the kernel code consistently uses the following
defines in hexadecimal:
SCSI_MLQUEUE_HOST_BUSY 0x1055
SCSI_MLQUEUE_DEVICE_BUSY 0x1056
SCSI_MLQUEUE_EH_RETRY 0x1057
SCSI_MLQUEUE_TARGET_BUSY 0x1058
Switch to using the string form of these values in the trace output:
dd-1059 [007] ..... 31.689529: scsi_dispatch_cmd_error: host_no=0 channel=0 id=0 lun=4 data_sgl=65 prot_sgl=0 prot_op=SCSI_PROT_NORMAL driver_tag=23 scheduler_tag=117 cmnd=(READ_10 lba=0 txlen=128 protect=0 raw=28 00 00 00 00 00 00 00 80 00) rtn=SCSI_MLQUEUE_DEVICE_BUSY
