i40e: Add new version of i40e_aq_add_macvlan function

Browse source

ASQ 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.

Add new _v2 version of i40e_aq_add_macvlan that is using
new _v2 versions of ASQ send command functions and returns
the Admin Queue status on the stack.
