Fix POSIX ACL use in el8+.

In 29160b0b I mistakenly disabled all caching of ACLs for el8
instead of only disabling cache lookups. The correct change
should have been to disable cache lookups only, and leave setting the
acl cache after storing or fetching, as the kernel needs this data
to resolve acls when doing permission checks.

Restore the acl cache insertions fixes.
