psplash: Avoid mount the psplash tmpfs twice

Browse Source 
The /etc/init.d/psplash.sh will be invoked both in boot and
shutdown/reboot. And the psplash tmpfs will be mounted twice. This
will trigger a bug in umount and let the system hang when
shutdown/reboot. I already made a patch [1] to fix the issue in
umount, but there is no reason for the psplash to do the twice mount.
So also fix it.
