packed-ring: fix queue size for pci

PCI is the only transport that has text enforcing
a power of two size for VQs. There's no real reason
for it to do it, so document that it does not apply
with the packed rings.

Accordingly, drop the text "unless enforced by a transport"
from packed ring description.
