firewire: don't panic on invalid AR request buffer
BUG() at this place is wrong. (Unless if the low level driver would already do higher-level input validation of incoming request headers.) Invalid incoming requests or bugs in the controller which corrupt the AR-req buffer needlessly crashed the box because this is run in tasklet context.
