compositor-fbdev: fix VT switching crash
This bug was introduced in 954f183e2f9891b241c1efc0ea61ed56019a4326.
The session_notify() data was accidentally cast to fbdev_backend while
it is weston_compositor. This was possibly due to the code before the
mentioned commit casting data directly to fbdev_compositor without going
through the intended type first, which worked only because
weston_compositor was the first member in struct fbdev_compositor.
Fix the casts to be the right way around.
