[ Upstream commit 4dde3c3627b52ca515a34f6f4de3898224aa1dd3 ]
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.
