Cache: ignore long locked entries during forced expire.

Abnormally exited workers may leave locked cache entries, this can
result in the cache size on disk exceeding max_size and shared memory
exhaustion.

This change mitigates the issue by ignoring locked entries during forced
expire.  It also increases the visibility of the problem by logging such
entries.
