OCV: Add support to override channel info OCI element (STA)

Browse source 
To support the STA testbed role, the STA has to use specified channel
information in OCI element sent to the AP in EAPOL-Key msg 2/4, SA Query
Request, and SA Query Response frames. Add override parameters to use
the specified channel while populating OCI element in all these frames.
