drm: stop scheduling while the session is paused

`render_surface` returns before clearing `redraw` on an inactive session, so every dispatch re-armed the deadline timer at refresh rate for as long as the user sat on another VT. After resume the stale `last_vblank_ns` and `target_ns` also produced a bogus missed-vblank and 30 s of extra slack in `Budget`.
