tree/workspace: fix output priority in workspace assignment

workspace_valid_on_output() and workspace_next_name() check whether an
output appears anywhere in a workspace's output list, ignoring priority
order. This allows a lower-priority output to claim a workspace even
when a higher-priority output is available.

Fix by stopping early when iterating the output list: if a different
available output is found before the current one, the workspace belongs
to that higher-priority output.
