[LEDE-DEV] [PATCH ubox] kmodloader: modprobe: return 0 for loaded modules

[Yousong Zhou]

This is the default behaviour with modprobe from kmod package [1] unless
it is explicitly told that the module is to be loaded for --first-time

 [1] http://www.kernel.org/pub/linux/utils/kernel/kmod/

Fixes FS#433
