Cache: fixed race in ngx_http_file_cache_forced_expire(). During configuration reload two cache managers might exist for a short time. If both tried to delete the same cache node, the "ignore long locked inactive cache entry" alert appeared in logs. Additionally, ngx_http_file_cache_forced_expire() might be also called by worker processes, with similar results. Fix is to ignore cache nodes being deleted, similarly to how it is done in ngx_http_file_cache_expire() since 3755:76e3a93821b1. This was somehow missed in 7002:ab199f0eb8e8, when ignoring long locked cache entries was introduced in ngx_http_file_cache_forced_expire().
