[PATCH weston] compositor: Always set output_mask in weston_surface_update_output_mask().

[Scott Moreau]

---

Commit 982387011 causes a bug where starting weston results in a black screen
(if no clients are immediately started). The problem is that the offending
commit causes the compositor to not damage if there is no difference in the
output_mask, which is the case when the compositor first starts. This patch
updates the surface output_mask unconditionally, whereas it stands currently,
might not be set due to the cases where we return immediately.
