Avoid a deadlock when CARP is used with if_bridge.
As if_bridge calls carp_forus() with the bridge lock held, there is a race where a carp callout can trigger just before the call to carp_forus() and, with the CARP lock held, will now wait for the bridge lock while the next call to carp_forus() is trying to acquire the CARP lock with the bridge lock held.
Ticket: #8056
(cherry picked from commit ab6cc9dd898d6ecb61a8758547ebb0916fe2dfb7)
