/etc/init.d/target doesn't work if configfs module is already loaded

[Marcus Sorensen <shadowsor@xxxxxxxxx>]

in this file, check_configfs_mount() checks for the existence of
/sys/kernel/config (which is created when configfs module is loaded).
If this does not exist, it modprobes configfs and mounts
/sys/kernel/config.  The problem is that if the system already has
configfs loaded for one reason or another then this script fails to
mount the configfs filesystem and nothing works.

I'm including a patch that seems to fix the issue for me, it simply
decouples the modprobe of configfs from the mounting of configfs.
