Commit 5c912e679506 ("usb: cdc-wdm: fix build error when CONFIG_WWAN_CORE is not set") fixed a build error when CONFIG_WWAN was set but CONFIG_WWAN_CORE was not. Since then CONFIG_WWAN_CORE was removed and joined with CONFIG_WWAN in commit 89212e160b81 ("net: wwan: Fix WWAN config symbols").

Also, since CONFIG_WWAN has class tri-state instead of bool, we cannot check if it is defined directly, but have to use IS_DEFINED() instead.
