wlan: Reduce Tx aggregation with Cisco AP in HT40 mode

Cisco AP has issues in receiving more than 25 "mpdu in ampdu"
causing very low throughput in HT40 case.
Currently at BA setup negotiation, DUT sends 0 window size in
AddBA request and Cisco responds with 64 which is causing
aggregate huge number of MPDUs.
DUT should send 25 as window size to force Cisco AP to
negotiate with lesser window size.
