dma-buf: Discard old fence_excl on retrying get_fences_rcu for reallocdrm-misc-next-2019-06-05
If we have to drop the seqcount & rcu lock to perform a krealloc, we
have to restart the loop. In doing so, be careful not to lose track of
the already acquired exclusive fence.
Fixes: fedf54132d24 ("dma-buf: Restart reservation_object_get_fences_rcu() after writes")
