[PATCH] wcn36xx: Set operational channel to 0 on disassociation

[Bryan O'Donoghue]

After a disassociated event we need to make sure we reset the operational
channel so that subsequent channel scans will not exclude the channel we
were using.

Doing a software scan on a wcn3680 showed that if we disassociated from an
AP we would never see it re-appear in a scan - unless we shifted the AP to
a different channel.

Setting the operational channel to zero on disassociation ensures that this
situation will not arise in the wild.
