Subject: [net-next 13/15] i40e: use cpumask_copy instead of direct assignment

From: Jacob Keller <jacob.e.keller@...el.com>

According to the header file cpumask.h, we shouldn't be directly copying
a cpumask_t, since its a bitmap and might not be copied correctly. Lets
use the provided cpumask_copy() function instead.
