firewire: core: record card index in tracepoinrts events derived from async_outbound_initiate_template

Browse Source 
The asynchronous transaction is initiated on one of 1394 OHCI controller,
however the existing tracepoints events has the lack of data about it.

This commit adds card_index member into event structure to store the index
of host controller in use, and prints it.
