[PATCH weston 1/2] compositor: fix comments about weston_compositor::surface_list

[Pekka Paalanen]

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

a7af70436b7dccfacd736626d6719b3e751fd985 converted the surface list into
a view list.

It looks like weston_surface::output's comment about surface list does
not apply to view list. Still, many places assume weston_surface::output
is not NULL when processing "visible" surfaces, e.g. those reachable via
the view list.

The comment on weston_view::output is updated, but I could not figure
out the actual relationship between that and being on the view list.

weston_view::link is documented to be in weston_compositor::view_list,
and weston_compositor::view_list is documented to contain weston_views.
