drm: add a check for x/y in drm_mode_setcrtc
commit 01447e9f04ba1c49a9534ae6a5a6f26c2bb05226 upstream.
legacy setcrtc ioctl does take a 32 bit value which might indeed
overflow
the checks of crtc_req->x > INT_MAX and crtc_req->y > INT_MAX aren't
needed any more with this
v2: -polish the annotation according to Daniel's comment
