FS-Cache: Add transition to handle invalidate immediately after lookup
Add a missing transition to the FS-Cache object state machine to handle an
invalidation event occuring between the back end completing the object lookup
by calling fscache_obtained_object() (which moves to state OBJECT_AVAILABLE)
and the backend returning to fscache_lookup_object() and thence to
fscache_object_state_machine() which then does a goto lookup_transit to handle
the transition - but lookup_transit doesn't handle EV_INVALIDATE.
Without this, the following BUG can be logged:
FS-Cache: Unsupported event 2 [5/f7] in state OBJECT_AVAILABLE
------------[ cut here ]------------
kernel BUG at fs/fscache/object.c:357!
Where event 2 is EV_INVALIDATE.
