firewire: core: clear sources of hardware interrupt at card removal

Due to the factors external to the system, hardware events may still be
handled while a card instance is being removed. The sources of hardware
IRQs should be cleared during card removal so that workqueues can be safely
destroyed.

This commit adds a disable callback to the underlying driver operations.
After this callback returns, the underlying driver guarantees that it
will no longer handle hardware events.
