Subject: [PATCH] net: iwlwifi: fix build error for IWLMEI

When CONFIG_IWLWIFI=m and CONFIG_IWLMEI=y, the kernel build system
must be told to build the iwlwifi/ subdirectory for both IWLWIFI and
IWLMEI so that builds for both =y and =m are done.

This resolves an undefined reference build error:

ERROR: modpost: "iwl_mei_is_connected" [drivers/net/wireless/intel/iwlwifi/iwlwifi.ko] undefined!

Fixes: 977df8bd5844 ("wlwifi: work around reverse dependency on MEI")
