qcacmn: Remove the unused varibale status from skip dfs API

Remove the unused varibale status, which is not initialized,
and hence returning of that varibale without any assignment
can lead to the API returning a non zero status (garbage value
as it is not initialized) which can lead to SAP restart
fail due to unsafe channel event received.

Fix is to remove the variable, and directly return success.
