igb: Check if num of q_vectors is smaller than max before array access



Ensure that the adapter->q_vector[MAX_Q_VECTORS] array isn't accessed
beyond its size. It was fixed by using a local variable num_q_vectors
as a limit for loop index, and ensure that num_q_vectors is not bigger
than MAX_Q_VECTORS.

Fixes: 047e0030 ("igb: add new data structure for handling interrupts and NAPI")
