drm/vmwgfx: Fix regression caused by "drm/ttm: make ttm reservation calls behave like reservation calls"
commit cf5e3413337309050c05e13dcebe85b7194a21e5 upstream.
The call to ttm_eu_backoff_reservation() as part of an error path would cause
a lock imbalance if the reservation ticket was not initialized. This error is
easily triggered from user-space by submitting a bogus command stream.
