[RFC PATCH 03/19] eventdev: fix variable shadowing issues

[Bruce Richardson <bruce.richardson@intel.com>]

Rename a macro variable to avoid shadowing conflicts, and reduce the
scope of another variable for the same reason.

Fixes: a3bbf2e09756 ("eventdev: add eth Tx adapter implementation")
Fixes: 7f33abd49b26 ("eventdev/eth_rx: support appropriately report idle")
Cc: stable@dpdk.org
