Subject: [PATCH net-next 2/7] i40e: Remove unused RX realloc stat

From: Joe Damato <jdamato@...tly.com>

After commit 1a557afc4dd5 ("i40e: Refactor receive routine"),
rx_stats.realloc_count is no longer being incremented, so remove it.

The debugfs string was left, but hardcoded to 0. This is intended to
prevent breaking any existing code / scripts that are parsing debugfs
for i40e.
