udldrmfb: udl_get_edid: usb_control_msg buffer must not be on the stack

commit 242187b362555849e8c971dfbbfd55f8bd9fa717 upstream.

The buffer passed to usb_control_msg may end up in scatter-gather list, and
may thus not be on the stack. Having it on the stack usually works on x86, but
not on other archs.
