selinux: make labeled NFS work when mounted before policy load
Bugzilla: https://bugzilla.redhat.com/show_bug.cgi?id=2218207
Tested: https://beaker.engineering.redhat.com/jobs/8121056
This merge request fixes the issue when NFS filesystem is not labeled correctly when mounted before SELinux loads (for example, root FS in diskless clients).
There is one minor conflict in security/selinux/hooks.c as selinux_initialized() still requires an argument.
