[dpdk-dev] [PATCH] net: virtio: clear reserved vring properly at setup time

[Maxime Coquelin]

After vring reservation, only the first bytes of the vring were
cleared.

This patch fixes this to clear the real size fo the vring.

Note: I found this bug while doing some code review, it is not a fix for
a problem I encountered.
