I made a mistake.

iwlwifi-m is automatically handled since commit
cf4f21938e13ea1533ebdcb21c46f1d998a44ee8
but cfg/*.o objects are not liked to vmlinux
under the following combination:

CONFIG_IWLWIFI=y
CONFIG_IWLDVM=m
CONFIG_IWLMVM=m


Please ignore this patch.

Perhaps, I may come back to this patch,
but I need to change scripts/Makefile.lib beforehand.
