Cache the count of shared fences in the iterator to avoid dereferencing
the dma_resv_object outside the RCU protection. Otherwise iterator and its
users can observe an incosistent state which makes it impossible to use
safely. Such as:

If the shared object has changed during the RCU unlocked period
callers will correctly handle the restart on the next iteration.

Ah, of course! I've been staring at the code the whole morning and
couldn't see it.
Going to write a testcase to cover that.

Maybe we should remove cursor->fences altogether, but either way the
patch is Reviewed-by: Christian König <christian.koenig@amd.com>
Please push to drm-misc-next ASAP.
