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).
