Make these two member variables available in debugfs such that
their value can be verified by kernel developers. An example of
the new output from a system with CONFIG_HZ=100:
ffff8804a41ed480 {.op=READ, .cmd_flags=META|PRIO, .rq_flags=MQ_INFLIGHT|IO_STAT, .atomic_flags=COMPLETE, .tag=17, .internal_tag=-1, .cmd=Read(10) 28 00 09 01 1f a0 00 00 08 00, .retries=0, .jiffies_at_alloc=-25647}
