selinux: fix missing dput() before selinuxfs unmount
Commit 0619f0f5e36f ("selinux: wrap selinuxfs state") triggers a BUG
when SELinux is runtime-disabled (i.e. systemd or equivalent disables
SELinux before initial policy load via /sys/fs/selinux/disable based on
/etc/selinux/config SELINUX=disabled).
This does not manifest if SELinux is disabled via kernel command line
argument or if SELinux is enabled (permissive or enforcing).
Before:
SELinux: Disabled at runtime.
BUG: Dentry 000000006d77e5c7{i=17,n=null} still in use (1) [unmount of selinuxfs selinuxfs]
After:
SELinux: Disabled at runtime.
Fixes: 0619f0f5e36f ("selinux: wrap selinuxfs state")
