qcacmn: Replace ap reg rules with client reg rules

Currently, there is no ap reg rules from the regdomain for
some countries. But function reg_append_mas_chan_list_for_6g_lpi
and reg_append_mas_chan_list_for_6g_vlp get the master chan per
the ap reg rules number. It casues it can't get the master chan
list for 6 GHz even it has client reg rules.

To resolve this issue, using num_of_6g_client_reg_rules instead of
num_of_6g_ap_reg_rules.
