hostapd: backport fix for wnm_sleep_mode=0
wpa_disable_eapol_key_retries can't prevent attacks against the Wireless Network Management (WNM) Sleep Mode handshake. Currently, hostapd processes WNM Sleep Mode requests from clients regardless of the setting wnm_sleep_mode. Backport Jouni Malinen's upstream patch 114f2830 in order to ignore such requests by clients when wnm_sleep_mode is disabled (which is the default).

+Subject: [PATCH] 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.
