qcacmn: Send the channel structure to check for ETSI preCAC

While checking if ETSI preCAC is already done on a given channel
in the API "dfs_is_etsi_precac_done", dfs_curchan is always used as
the channel to be checked. Since the API "dfs_is_cac_required" maybe
called without updating the dfs_curchan, using dfs_curchan in
function "dfs_is_etsi_precac_done" is not correct.
Use the current channel provided to the API "dfs_is_cac_required"
as input while checking for ETSI preCAC.
