ath9k: dynack: set ackto to max timeout in ath_dynack_reset

Browse Source 
Initialize acktimeout to the maximum configurable value in
ath_dynack_reset in order to not disconnect long distance static links
enabling dynack and even to take care of possible errors configuring
a static timeout. Moreover initialize station timeout value to the current
acktimeout value
