igb: Do not free q_vector unless new one was allocated

In the Linux kernel, the following vulnerability has been resolved:

igb: Do not free q_vector unless new one was allocated

Avoid potential use-after-free condition under memory pressure. If the
kzalloc() fails, q_vector will be freed but left in the original
adapter->q_vector[v_idx] array position.

CWE-416 Use After Free

The product reuses or references memory after it has been freed. At some point afterward, the memory may be allocated again and saved in another pointer, while the original pointer references a location somewhere within the new allocation. Any operations using the original pointer are no longer valid because the memory "belongs" to the code that operates on the new pointer.
