ath9k: Fix FIF_BCN_PRBRESP_PROMISC handling

This is a port of commit
91ed19f5f66a7fe544f0ec385e981f43491d1d5a
for 2.6.29.

Without this after scanning your device will set
the association ID to something bogus and what is
being reported is multicast/broadcast frame are not
being received. For details see this bug report:

https://bugzilla.redhat.com/show_bug.cgi?id=498502

>From the original commit:

So that a new created IBSS network
doesn't break on the first scan.

It seems to Sujith and me that this
stupid code unnecessary, too.

So remove it...
