[PATCH weston] exposay: fix crash when navigating with the keyboard

[Emilio Pozuelo Monfort]

From: Emilio Pozuelo Monfort <emilio.pozuelo at collabora.co.uk>

Commit a7592019 introduced an optimization that caused some
exposay struct members to not be properly initialized, particularly
cur_output, leading to crashes in some circumstances (e.g. pressing
the down arrow key after going to exposay).
