kmod_modprobe: Fix regression when inserting module
kmod_modprobe: Fix regression when inserting module

Commit "e5e2a68 kmod_modprobe: properly handle install/remove commands"
introduced a regression that, while it worked for install/remove
commands, it ceased to work for normal module names. Move the check for
whether it's a install command or a module so both cases work.
