Currently, when adding or deleting MAC addresses, we are using
rte_zmalloc followed by an immediate rte_free. This is not needed as this
memory is not being stored anywhere, so replace it with regular
malloc/free.

Given the loop above has a threshold set for IAVF_AQ_BUF_SZ, maybe a static
buffer of that fixed size might be better?

Also, that check itself seems a little off, since it allows buffers greater
than the size, rather than ignoring the length of the address that pushes
it over the limit.

Fun fact: this entire thing is pointless, because sizeof() of MAC address structure is 8 bytes, there's max 64 addresses, and the buffer is 4K so it will *never* overflow and need to be split up. I'll remove that code.
