igb: set num_rx/tx_queues to 0 when queues are freed
An issue was seen on suspend in which the system reported a page fault. This
was due to the new reg_idx code being called after the queues were freed.
This update prevents any for loops from going through the queues by setting
the number of queues to 0 when they are freed.
