nvme: add tracepoint for nvme_setup_cmd
Add tracepoints for nvme_setup_cmd() for tracing admin and/or nvm commands.
Examples of the two tracepoints are as follows for trace_nvme_setup_admin_cmd():
kworker/u8:0-5 [003] .... 2.998792: nvme_setup_admin_cmd: cmdid=14, flags=0x0, meta=0x0, cmd=(nvme_admin_create_cq cqid=1, qsize=1023, cq_flags=0x3, irq_vector=0)
and trace_nvme_setup_nvm_cmd():
dd-205 [001] .... 3.503929: nvme_setup_nvm_cmd: qid=1, nsid=1, cmdid=989, flags=0x0, meta=0x0, cmd=(nvme_cmd_read slba=4096, len=2047, ctrl=0x0, dsmgmt=0, reftag=0)
