RX descriptors should be reinitialized in rx_fill(), which is a function for setting up RX descriptors.

Description
This PR is one of a series of PRs that consolidates previous network improvement work. In this PR specifically, it eliminates copying when passing from the network driver to if_net.
While there are currently three implemented network device drivers - Ixgbe, Igb, and Genet - this PR does not include support for Genet. This will be tracked as an issue #256. This limitation is also documented in the source code comments.
