kmod_modprobe: fix handling of remove commands

The check for remove/install commands must be before the ignore_loaded
check because we will actually run something instead of
removing/inserting a module and the modname might not correspond to a
real module. Otherwise a fake module like "remove removeme echo 'bla'"
would not work.

This also keeps compatibility with modprobe.
