firewire: core: add tracepoints events for asynchronous outbound response
In a view of core transaction service, the asynchronous outbound response
consists of two stages; initiation and completion.
This commit adds a pair of events for the asynchronous outbound response.
The following example is for asynchronous write quadlet request as IEC
61883-1 FCP response to node 0xffc1.
async_response_outbound_initiate: \
transaction=0xffff89fa08cf16c0 generation=4 scode=2 dst_id=0xffc1 \
tlabel=25 tcode=2 src_id=0xffc0 rcode=0 \
header={0xffc16420,0xffc00000,0x0,0x0} data={}
async_response_outbound_complete: \
transaction=0xffff89fa08cf16c0 generation=4 scode=2 status=1 \
timestamp=0x0000
