qcacld-3.0: Remove unused code from driver

Presently, while sending scan offload request to fw, fw is only notified
whether the channel list is static or dynamic. Fw is not notified whether
it is dynamic init, dynamic flush or dynamic update. Also, in HOST
driver it is not being used anywhere.

Remove the code to mark the channel list as dynamic update, dynamic flush
or dynamic init. Instead, assign the channel list simply as dynamic.
