xprops: Use g_new0 instead of calloc in meta_prop_get_motif_hints()

Browse Source 
Use g_new0 instead of calloc for motif_hints_from_results and adjust
its callers to use g_free.

Note that in the process_request_frame_extents function this replaces
the wrong original mismatch of calloc + XFree with a matching g_malloc +
g_free pair.
