xwayland: use g_autoptr for GError in xserver_died

Browse Source 
Right now we explicitly g_clear_error any error we find, but that
makes it tricky to return early from the function, which a
subsequent commit will want to to do.

This commit switches GError to use g_autoptr so the error clearing
happens automatically.
