Revert "qcacld-3.0: Flush scan results on interface down"

Browse source 
This reverts the change id- I3505c128276fa8e5e05ea5d9110eb75275a746e9.

When wifi is toggled from GUI, in order to support MAC randomization
security mechanism  driver should not flush scan cache during interface
down. Framework has to set the scan flush flag so that driver will flush
the scan results while interface up and then do the scan.

Remove scan flush logic from driver on interface down.
