Release RX and TX resources on the boundary of the

These functions contribute to rolling back a partial, failed initialization
of the virtio-net SNP driver instance, or to shutting down a fully
initialized, running instance.
They are only callable by the VirtioNetInitialize() and the
VirtioNetShutdown() SNP methods. See the state diagram in "VirtioNet.h".
