firewire: core: record card index in bus_reset_handle tracepoints event
The bus reset event occurs in the bus managed by one of 1394 OHCI
controller in Linux system, however the existing tracepoints events has
the lack of data about it to distinguish the issued hardware from the
others.
This commit adds card_index member into event structure to store the index
of host controller in use, and prints it.
