Registering the handler after both GPUs will trigger a DDC switch for
connector reprobing. This will oops if apple_gmux_data hasn't already
been assigned. Reorder the code to do that.
[Lukas: More generally, this commit fixes a race condition that
is triggered by invoking a handler callback between the call to
vga_switcheroo_register_handler() and the assignment of
apple_gmux_data.]
