Takashi Sakamoto 944b06840a firewire: core: add tracepoints events for asynchronous outbound request
In a view of core transaction service, the asynchronous outbound request
consists of two stages; initiation and completion. This commit adds a pair
of event for them.

The following example is for asynchronous lock request with compare_swap
code to offset 0x'ffff'f000'0904 in node 0xffc0.

async_request_outbound_initiate: \
  transaction=0xffff955fc6a07a10 generation=5 scode=2 dst_id=0xffc0 \
  tlabel=54 tcode=9 src_id=0xffc1 offset=0xfffff0000904 \
  header={0xffc0d990,0xffc1ffff,0xf0000904,0x80002}
  data={0x80,0x940181}
async_request_outbound_complete: \
  transaction=0xffff955fc6a07a10 generation=5 scode=2 status=2 \
  timestamp=0xd887
