Subject: [PATCH 4.14 066/114] i40iw: Fix error handling in i40iw_manage_arp_cache()

From: Dan Carpenter <dan.carpenter@...cle.com>

[ Upstream commit 37e31d2d26a4124506c24e95434e9baf3405a23a ]

The i40iw_arp_table() function can return -EOVERFLOW if
i40iw_alloc_resource() fails so we can't just test for "== -1".

Fixes: 4e9042e647ff ("i40iw: add hw and utils files")
