Fix memory realted to #64726
Also fixed bug #64726 in 5.3
fix possible null deref (detected by code coverity scan)
unused variable
use limit_extensions as we use security_limit_extensions later (free)
fixed size array cannot be null
From code coverity scan
- fix some memory leak
- fix some resources leak (fd)
- create fpm_worker_pool_free (shared use)
- possible null dref (wp->user and wp->home can be null)
fix more resource leaks
From code coverity scan, syscall return value must be check.

To not alter current behaviour, we simply log the problem,
so, if it occurs, the message will give explanation.

This are only warning as they don't block the server,
but such fail can explain strange (not expected) behaviour later.
