window-x11: Refactor meta_prop_get_latin1_string() calls

Browse Source 
Instead of storing the result of meta_prop_get_latin1_string() into
a temporary string value, g_strdup-ing that temp value storing the
g_strdup result into window->sm_client_id and then g_free-ing the
temporary string, we can pass window->sm_client_id as the place where
meta_prop_get_latin1_string() stores its result, since the result
from meta_prop_get_latin1_string() is itself a g_strdup-ed string,
so there is no need to g_strdup it again.

Note this drops the check to only issue the
"Window %s sets SM_CLIENT_ID on itself ..." warning once. This check is
not necessary as update_sm_hints() is only called once at window
creation time and is never called again.
