Backtrace of the crash.

Start weston-editor, the input panel (virtual keyboard) should open. Start a
new weston-editor, weston then crashes.

The backtrace is attached, and it's possible to see that inside the
input_panel_configure() function, right before weston_slide_run, the
view->output is NULL. It should be assigned to something else in the
weston_view_update_transform(), but that function returns earlier because the
transform is not dirty.

A simple workaround of assigning that output fixes the problem. But I'm not
sure if it should be already assigned somewhere else when it reaches this point
of the code.

Anyway, a workaround is simple and should fix it.
