WNM: Ignore WNM-Sleep Mode Request in wnm_sleep_mode=0 case

The hostapd wnm_sleep_mode parameter was previously used to control
advertisement of WNM-Sleep Mode support, but it was not used when
processing a request to use WNM-Sleep Mode. Add an explicit check during
request processing as well so that any misbehaving station is ignored.
