af_xdp: fix stale rx/tx pointers in xsk objects

xsk objects keep pointers to the rx and tx objects. If we re-allocate
the rx and tx vectors after initializing the associated xsk object, the
pointers in the xsk object will be staled.
To avoid this, we allocate the vectors to the max expected size instead
of growing them.

Type: fix
