BFD: Fix crash related to reconfiguration and passwords

Any change in BFD iface configuration should trigger session
reconfiguration, as config is copied into the bfd_session structure
and not just accessed through the bfd_iface structure.

As bfd_session now contains a pointer to the password list allocated
from the configuration, forgetting to update the bfd_session causes
use-after-free.

Thanks to Lexi Winter for the bugreport.
