When a view was destroyed while we were on exposay, we didn't
remove it from the list of views, and so when leaving exposay
we were trying to animate (and sometimes activate) a
non-existent view, causing a crash.

exposay_highlight_surface() is called from exposay_pick(),
exposay_layout(), and exposay_maybe_move() where the esurface
parameter is already validated prior to the call. This makes
the 'esurface' NULL check redundant. This assumes any future
calls to exposay_highlight_surface() will also validate the
'esurface' parameter prior to the call.
This fixes the logic in exposay_highlight_surface so static
analyzers don't complain about the possibility that 'view'
might be NULL deref'd when a 'esurface' == NULL condition is
true.

We were calling exposay_highlight_surface() inside a wl_list_for_each
loop for a layer, but exposay_highlight_surface() calls activate()
which calls shell_surface_update_layer(), which removes the surface
from its layer and reinserts it, causing an infinite loop.
Call exposay_highlight_surface() outside the for_each to avoid this.
