[PATCH] net/nfp: fix skip reload firmware issue

[Chaoyong He]

From: Peng Zhang <peng.zh...@corigine.com>

When the beat value of all ports are 0, which represent all
ports are unused. But the current port starts beat before
the check process, so it needs to sleep 1 second waiting
the beat value change and to ignore the current port.

Fixes: 8b9a83ea2af2 ("net/nfp: enlarge range of skipping loading firmware")
