From: Mordechay Goodstein <mordechay.goodstein@xxxxxxxxx>
Currently channel context is updated only after station got an update about
new assoc state, this results in station using the old channel context.
Fix this by moving the update channel context before updating station,
enabling the driver to immediately use the updated channel context in
the new assoc state.
