nat: report correct EI per-user session limit
Type: fix When enabling the endpoint independent NAT44 plugin, user_sessions determines the maximum number of translations that can be active for a single inside address. If 0 is passed in, a default value is used but 0 is still stored in the field that is used to populate reply messages to nat44_ei_show_running_config, At the time of enabling the plugin, if user_sessions is 0, update the field which is used by nat44_ei_show_running_config to contain the default per-user limit which gets used by the EI nodes.
