[RFC] mac80211: Change BA timeout

[Sujith <m.sujith@gmail.com>]

The BlockAck session timout value is currently an arbitrary 5000.
This results in BA sessions being created and torn down incessantly
when mac80211 is used with a driver (say ath9k) in AP mode.

The 802.11 standard doesn't specify any default value for the timeout field.
And there is no benefit to be gained by tearing down BA sessions and
recreating them. The current value of 5000 doesn't cause any problems,
but it is hard to find an AP/STA in the field that uses a non-zero timeout.
