Make these two member variables available in debugfs such that their
value can be verified by kernel developers. An example of the new
output:
ffff8804a513d480 {.op=READ, .cmd_flags=META|PRIO, .rq_flags=MQ_INFLIGHT|DONTPREP|IO_STAT|STATS, .atomic_flags=STARTED, .tag=17, .internal_tag=-1, .cmd=Read(10) 28 00 08 81 32 38 00 00 08 00, .retries=0, allocated 0.010 s ago}
