firewire: core: record card index in async_phy_outbound_complete tracepoints event

Browse Source 
The asynchronous transmission of phy packet 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.
