ASQ(Admin Send Queue) send command functions are returning only i40e
status codes yet some calling functions also need Admin Queue status that
is stored in hw->aq.asq_last_status. Since hw object is stored on a heap
it introduces a possibility for a race condition in access to hw if
calling function is not fast enough to read hw->aq.asq_last_status before
next send ASQ command is executed.
Added new versions of send ASQ command functions that return Admin Queue
status on the stack to avoid race conditions in access to
hw->aq.asq_last_status.
Added new _v2 version of i40e_aq_remove_macvlan and i40e_aq_add_macvlan

On the vector implementation, during the tear-down, the mbufs not
drained in the RxQ and TxQ are freed based on an algorithm which
supposed that the number of descriptors is a power of 2 (max_desc).
Based on this hypothesis, this algorithm uses a bitmask in order to
detect an index overflow during the iteration, and to restart the loop
from 0.
However, there is no such power of 2 requirement in the ixgbe for the
number of descriptors in the RxQ / TxQ. The only requirement is to have
a number correctly aligned.
If a user requested to configure a number of descriptors which is not a
power of 2, as a consequence, during the tear-down, it was possible to
be in an infinite loop, and to never reach the exit loop condition.
By removing the bitmask and changing the loop method, we can avoid this
issue, and allow the user to configure a RxQ / TxQ which is not a power
of 2.
