nvme-tcp: add additional info for nvme_tcp_timeout log
This provides additional details about the rq/cmd that is timed out
example log if CONFIG_NVME_VERBOSE_ERRORS is configured:
"nvme nvme0: queue 2 timeout cid 0xd058 type 4 opc Write (0x1)"
example log if CONFIG_NVME_VERBOSE_ERRORS is not configured:
"nvme nvme0: queue 2 timeout cid 0xd058 type 4 opc I/O Cmd (0x1)"
