Stefan Richter e9aeb46c93 firewire: fully initialize fw_transaction before marking it pending
In theory, card->flush_timer could already access a transaction between
fw_send_request()'s spin_unlock_irqrestore and the rest of what happens
in fw_send_request().  This would happen if the process which sends the
request is preempted and put to sleep right after spin_unlock_irqrestore
for longer than 100ms.

Therefore we fill in everything in struct fw_transaction at which the
flush_timer might look at before we lift the lock.

To do:  Ensure that the timer does not pick up the transaction before
the time of the AT request event plus split transaction timeout.
