qcacmn: Add support to ignore DCS FW event for low cycle count

In the api wlan_dcs_wlan_interference_process(), the XPAN
sap initiate multiple CSA when the rx clear cnt
is above threshold. This frequent XPAN SAP CSA is
not expected.

Add support to check the cycle count to be lower than
rx clear count value to prevent frequent initiation of CSA.
