In the case of finite Spectral scan, the spectral scan will be stopped in
the target once the requested count of spectral reports got generated.
The Host will not be notified of this stop scan. To synchronize the Host
data structures in accordance with the target, we explicitly stop the scan
once the last report is received. In the current implementation, the
stop_scan() is called at the beginning of the last report processing and
we continue processing the last report. As part of the last report
processing, we could access the data structures that were reset during
the stop_scan(). To fix this, stop the spectral scan at the end of the
last report processing.
