Problem:
STA's connectivity state machine gets into a loop of sending
disassociation, for previously disassociating STA when no ACK
is received for Association Response within ap_handle_timer timeout.
To Fix this issue, move the
sta->timeout_next = STA_NULLFUNC;
from handle_assoc() to hostapd_new_assoc_sta().
sta->timeout_next is set to STA_NULLFUNC only when Ack is received
for the Association Response sent out. So if ACK is not received
within AP_DEAUTH_DELAY, STA is deauthenticated and STA context is
cleaned up. Due to which there needs to be a new session started
by STA with AUTH Req.
