Some vendors want to add a field when a 'sruct nf_conn' is added so give a hook to handle this. Any memory allocated when trace_android_rvh_nf_conn_alloc() is called needs to be freed when trace_android_rvh_nf_conn_free() is called. Note, if trace_android_rvh_nf_conn_alloc() fails, be sure to be able to handle this in trace_android_rvh_nf_conn_free(), but that should not be an issue as that needs to be addressed in vendor code that runs for 'struct nf_conn' objects that have been created before the vendor code is loaded no matter what.
