firewire fixes for 6.12-rc5

This update includes a single commit to resolve a regression existing in
v6.11 or later.

The change in 1394 OHCI driver in v6.11 kernel could cause general
protection faults when rediscovering nodes in IEEE 1394 bus while holding
a spin lock. Consequently, watchdog checks can report a hard lockup.

Currently, this issue is observed primarily during the system resume phase
when using an extra node with three ports or more is used. However, it
could potentially occur in the other cases as well.
