r19391: Fix crash bug within the winbind caching method.

Browse Source 
That one was hard to find: when coming from offline mode and switching
to online, a refresh sequence number call (using the default MS-RPC
mechanism) may reset domain->backend to NULL (by the set_domain_online
event). We need to make sure to reidentify the remote domain in that
case.
