fix: mStopIfError/GetMacAddr/get_ipstr_to_array 误被 #if NET_SSC_ENABLE 排除

这些共享函数被包裹在 #if NET_SSC_ENABLE 中导致链接失败：
- mStopIfError — net_srv_init 调用
- GetMacAddr     — peripheral_main 调用
- get_ipstr_to_array — tcp_json_srv 调用

修复：在 clear_mqtt_buf 后关闭 #if，mStopIfError 后重开；
在 poll_mqtt 后关闭 #if，get_ipstr_to_array 后重开
