qcacmn: Make agile center freq 0 in stop sscan

In agile spectral scan scenario, if there is a chan switch,
it is possible for the new operating span to overlap with
the agile frequency, which results in erroneous outcome.

Make agile center freq 0 as part of every stop agile
scan. This ensures that a new frequency is mandated
as part of every agile scan.
