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().
