Currently, BTM offload config from the ini is sent to the FW as part
of the RSO start for the vdev which has roaming enabled. In case
of STA+STA concurrency, when roaming is enabled for second STA,
BTM config is sent for the second STA vdev leading the FW to assert
as the FW already has BTM offload enabled for the previous STA
session and supports only one vdev with BTM offload enabled at a time.
Send BTM offload config with flags as disabled as part of RSO Stop
so that the FW de-inits the BTM offload on the current connected vdev
before it inits BTM offload config on the new vdev for the second STA.
