[PATCH v5 13/34] net/ixgbe: decouple scalar and vec rxq free mbufs

[Anatoly Burakov]

Currently, vector Rx queue release mbufs function is only called from
inside the scalar variant. Decouple them to allow both to be defined
separately from each other, and provide a common function that picks
between the two when necessary.
