Patch from Egor Duda

Attached patch prevents modprobe from trying to call 'insmod (null)'
whenever nonexistent module is either passed to modprobe via command
line or mentioned in modules.dep

this replaces cryptic error
sh: Syntax error: word unexpected (expecting ")")
with
modprobe: module some-module not found.

egor.
