vt: remove VT_RESIZE and VT_RESIZEX from vt_compat_ioctl()

[ Upstream commit c4c7ead7b86c1e7f11c64915b7e5bb6d2e242691 ]

They are listed amon those cmd values that "treat 'arg' as an integer"
which is wrong. They should instead fall into the default case. Probably
nobody ever relied on that code since 2009 but still.
