rtl8139: Disallow chaining above 64K

[QEMU] rtl8139: Disallow chaining above 64K
As it stands the 8139C+ TX chaining is only bounded by realloc failure.
This is contrary to how the real hardware operates. It also has DoS
potential when ioemu runs in dom0.
This patch makes any attempt to chain a frame beyond 64K fail
