net: bridge: Fix uninitialized error in br_fdb_sync_static()
With gcc-4.1.2.:
net/bridge/br_fdb.c: In function ‘br_fdb_sync_static’:
net/bridge/br_fdb.c:996: warning: ‘err’ may be used uninitialized in this function
Indeed, if the list is empty, err will be uninitialized, and will be
propagated up as the function return value.
Fix this by preinitializing err to zero.
Fixes: eb7935830d00b9e0 ("net: bridge: use rhashtable for fdbs")
