Subject: [PATCH] vb2: Fix an off by one error in 'vb2_plane_vaddr'

commit 5ebb6dd36c9f5fb37b1077b393c254d70a14cb46 upstream.

We should ensure that 'plane_no' is '< vb->num_planes' as done in
'vb2_plane_cookie' just a few lines below.

Fixes: e23ccc0ad925 ("[media] v4l: add videobuf2 Video for Linux 2 driver framework")
