[PATCH] netxen: fix incorrect loop counter decrement

[Colin King]

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

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")
