staging: fbtft: fix unchecked write return value in fb_agm1264k-fl

Browse Source 
The second call to par->fbtftops.write() does not capture the return
value, so the subsequent error check tests a stale value from the
first write call. Add the missing assignment so the error check
applies to the correct write operation.
