lacp: fix regarding vm arg for vlib_time_now calls

Use thread-specific vlib_main_t *vm pointers to avoid problems with
different threads accessing the same vlib_main_t data structure.
This avoids assertion failure when vlib_time_now() is called with a vm
corresponding to a different thread.

Type: fix
