UPSTREAM: staging: android: vsoc: fix copy_from_user overrun
The `np->permission' structure is smaller than the `np' structure but
sizeof(*np) worth of data is copied in there. Fix the size passed to
copy_from_user() to avoid overrun.
Fixes: 3d2ec9dcd553 ("staging: Android: Add 'vsoc' driver for cuttlefish.")
