From: Colin Ian King <colin.k...@canonical.com>
A recent compat change removed the copying of i32.mode from info.mode.
Add it back in to fix this removal as we currently are leaking information
from the stack.
Detected by CoverityScan, CID#1449374 ("Unitialized scalar variable")
Fixes: 2337f2272ee1 ("compat_drm: switch AGP compat ioctls to
drm_ioctl_kernel()")
