[PATCH wayland] server: Add doxygen comment for wl_client_for_each

[Yong Bakos]

From: Yong Bakos <ybakos at humanoriented.com>

Commit 596024f728b0a1292ee69a80dd72a85167870936 includes a doc comment
with a link to the wl_client_for_each macro, causing an error when generating
documentation.

Add a doc comment to wl_client_for_each, enabling the hyperlink and removing
the error.
