qca-wifi: Reset unassoc entries for every cfr_pdev_open

After every wifi up/down or load/unload, it is expected that
cfr enabled entries should be reset. Earlier, associated clients'
entires are cleared by FW. Unassociated entries are maintained by
host and were not cleared. This change clears them properly at
cfr_pdev_open level
