net/bnxt: fix memzone free for Tx and Rx rings

[ upstream commit 64a4d59 ]

The device cleanup logic was freeing most of the ring related memory,
but was not freeing up the memzone associated with the rings.
This patch fixes the issue.

Fixes: 2eb53b1 ("net/bnxt: add initial Rx code")
Fixes: 6eb3cc2 ("net/bnxt: add initial Tx code")
