crimson/osd/pg: discard watches' states after iterating all cached obcs

Discarding watches' states while iterating cached obcs might have the
following problem:

1. discard a watch's state
2. the corresponding object context's use_count drops to zero
3. the object context is unreferenced by obc lru
4. obc is deleted from obc lru by lru's evict()
5. obc iteration is corrupted
