[PATCH weston 3/4] desktop-shell: do not lower_fullscreen_layer(s, NULL)

[Fabien Lahoudere]

From: Pekka Paalanen <pekka.paalanen at collabora.co.uk>

In activate, do not call lower_fullscreen_layer() at all if the output
is NULL. It should not do anything in that case, per the existing
comment.

This is a tentative crash fix for a case where there are no enabled
weston_outputs at all.
