firewire: core: abort pending transactions at card removal
IEEE 1394 defines the split, concatenated, and unified transaction.
To support the split transaction, core function uses linked list to
maintain the transactions waiting for acknowledge packet. After clearing
sources of hardware interrupts, the acknowledge packet is no longer
handled, therefore it is required to abort the pending transactions.
This commit executes callback with RCODE_CANCELLED for the pending
transactions at card removal.
