This check is a remnant of the libselinux <2.5 era, back when
is_selinux_enabled() checked whether a policy had been loaded. Nowadays
it only checks whether selinuxfs is mounted, and "load_policy -i"
therefore incorrectly refuses operation when selinuxfs is mounted, but
no policy has been loaded yet.
While it doesn't make much sense to call selinux_init_load_policy()
twice, there's no harm in doing so either, so let's just drop this
safeguard instead of fixing it.
