ceph: don't leak snap_rwsem in handle_cap_grant

When handle_cap_grant is called on an IMPORT op, then the snap_rwsem is
held and the function is expected to release it before returning. It
currently fails to do that which could lead to a deadlock.

Ensure it releases the snap_rwsem if this is an IMPORT op.
