qcacmn: Add wifi configuration attribute restrict offchannel

This commit defines an attribute to
QCA_NL80211_VENDOR_SUBCMD_SET_WIFI_CONFIGURATION -
QCA_WLAN_VENDOR_ATTR_CONFIG_RESTRICT_OFFCHANNEL which can be used to
restrict offchannel operations on the AP/GO interface.

The goal is to restrict any operations which would cause the AP/GO to
leave its operating channel.
