qcacld-3.0: Get country code using wlan_reg_read_current_country

In lim_handle_csa_offload_msg(), mac->scan.countryCodeCurrent is
passed in regulatory API wlan_reg_dmn_get_chanwidth_from_opclass
to get the opclass. mac_ctx->scan.countryCodeCurrent is no more
updated after the regulatory componentization so get country
using wlan_reg_read_current_country() instead of it.
