uterm: vt: fix resetting access control on VT-close

Browse Source 
This is a weird fix. One would think that this is automatically reset when
calling close() on the fd but, suprise, it's not. So lets reset this
manually, otherwise when we close the VT but our application is still
active, the user will never be able to leave the VT again.

Again a hilarious example why the VT API sucks. Really... Get rid of it.
