Andy Pei e579172633 net/ipn3ke: use control thread to check link status 
ipn3ke driver creates a thread to check link status.

Before this patch, pthread_create() is used to create
thread, leaving the new thread unrestrained wrt cpu
affinity.

After this patch, rte_ctrl_thread_create() is used to
create thread. The affinity of the new thread is based
on the CPU affinity retrieved at the time rte_eal_init()
was called, the dataplane and service lcores are then
excluded.

Fixes: 70d6b7f550 ("net/ipn3ke: add representor")
