ath9k: Fix offchannel operation 

When multiple channel contexts are active, an offchannel
request will not be handled immediately, but will be
queued to be handled later. But, currently, the channel definition
is not copied to the local offchannel state. This
breaks operation like scanning when MCC is active.

Fix this by storing the offchannel parameters properly.
