In wlan_hdd_cfg80211_start_bss(), beacon head buffer is typecast
to ieee80211_mgmt structure without checking for buffer length
against beacon header length which may cause OOB access
while accessing iee80211_mgmt structure.
To address this, add check for beacon head length against beacon
header length before typecasting to iee80211_mgmt structure.
Also while accessing supported rates, length given to function
wlan_hdd_cfg80211_get_ie_ptr() is the total length of management
frame that also includes header length which may cause OOB access
while getting supported rates.
To address this, send only beacon data length and exclude header
length to function wlan_hdd_cfg80211_get_ie_ptr().
