Description
This commit removed the rbd device snapshot list:
17e4749 rbd: kill off the snapshot list
It inadvertently removed the code that cleared
the EXISTS flag from removed snapshots (something
noted by ace reviewer Josh Durgin.
That needs to go back. Just scan the snapshot
context to see if it is found in the array, and
if not, clear the flag.

The following patches have been posted for review.
They are available in the "review/wip-slabs" branch
of the ceph-client git repository.
The first patch in this series puts back some functionality
that was deleted inadvertently by the previous commit. Josh
pointed out it had disappeared. The second one replaces a
linear search of snapshot ids with a binary search for
efficiency.
