The value of GINTMSK2 hasn't been checked since the inception of
dwc2_gadget_wkup_alert_handler() in 2018.

Fixes the following W=1 warning:

 drivers/usb/dwc2/gadget.c: In function ‘dwc2_gadget_wkup_alert_handler’:
 drivers/usb/dwc2/gadget.c:259:6: warning: variable ‘gintmsk2’ set but not used [-Wunused-but-set-variable]
 259 | u32 gintmsk2;
 | ^~~~~~~~
