netfilter: bridge: remove BRNF_STATE_BRIDGED flag
Its not needed anymore since 2bf540b73ed5b
([NETFILTER]: bridge-netfilter: remove deferred hooks).
Before this it was possible to have physoutdev set for locally generated
packets -- this isn't the case anymore:
BRNF_STATE_BRIDGED flag is set when we assign nf_bridge->physoutdev,
so physoutdev != NULL means BRNF_STATE_BRIDGED is set.
If physoutdev is NULL, then we are looking at locally-delivered and
routed packet.
