qcacld-3.0: Fix FW assert for RSO disabled before stopped

During roaming sync, disconnect happens from osif for some reason,
RSO_STOP is dropped for reason
RREASON_DRIVER_DISABLED/REASON_ROAM_STOP_ALL,  RSO_DISABLE is sent to
F/W for different reason REASON_DISCONNECTED. RSO_DISABLE happened
without RSO_STOP before,  so F/W assert.

To fix it, for disconnect from osif, set RSO_STOP reason as
REASON_DISCONNECTED, same as RSO_DISABLE REASON_DISCONNECTED, then it can
be sent to F/W during roam sync.
