[PATCH 3.16 120/294] netxen: fix incorrect loop counter decrement

[Ben Hutchings]

3.16.50-rc1 review patch.  If anyone has any objections, please let me know.

------------------

From: Colin Ian King <colin.k...@canonical.com>

commit a120d9ab65354727559b9db75ded8071b7ef19e2 upstream.

The loop counter k is currently being decremented from zero which
is incorrect. Fix this by incrementing k instead

Detected by CoverityScan, CID#401847 ("Infinite loop")

Fixes: 83f18a557c6d ("netxen_nic: fw dump support")
