This patch cleans up a couple of crashes caused by libselinux

If you fail to load_policy in the init or SELinux is disabled, you need
to free the selinux_mnt variable and clear the memory.
systemd was calling load_polcy on a DISABLED system then later on it
would call is_selinux_enabled() and get incorrect response, since
selinux_mnt still had valid data.
The second bug in libselinux, resolves around calling the
selinux_key_delete(destructor_key) if the selinux_key_create call had
never been called. This was causing data to be freed in other
applications that loaded an unloaded the libselinux library but never
setup setrans or matchpathcon.
