qcacld-3.0: Validate ini for standalone SAP CSA

Currently if sta_sap_scc_on_dfs_chnl is disabled,
standalone sap can come up on DFS channel in non-dbs
hw but standalone sap channel switch to dfs is rejected
by hdd in case of non-dbs hw and with disabled
sta_sap_scc_on_dfs_chnl.

Fix is not to reject standalone sap csa request for
DFS channel on non-dbs hw if sta_sap_scc_on_dfs_chnl is
disabled, as standalone sap can come up on DFS channel
when sta_sap_scc_on_dfs_chnl is set to 0.
