description:
#if 0 the declaration and definition of xennetback_tx_free()

Since it is never otherwise referenced, this cannot make any
current operational difference, but should fix the build.
(-Werror=unused-function)

The added #if/#endif lines are /* XXX */ commented, so they will be
easy to remove when needed.
