qcacld-3.0: Offload BTM to FW supplicant disabled-roam only

Issue is Host always sends btm_offload bitmap as 1 via RSO
STOP command during disconnection. If host configures BTM
enable with flag value as 1 during disconnection and try to
enable back with flag value 0x1c1, FW will never honor it
since previous configuration is not disabled while
disconnection.

FW expects BTM offload enable only as part of supplicant
disabled-roam and btm_offload bitmap to be cleared (= 0)
in RSO STOP during disconnection.

Fix is to set btm_offload bitmap as 1 only while processing
RSO STOP with roam reason REASON_SUPPLICANT_DISABLED_ROAMING.
