[PATCH v3] net/bonding: fix bond startup failure when NUMA is -1

[Chaoyong He]

From: Zerun Fu <zerun.fu at corigine.com>

After the mainline Linux kernel commit
"fe205d984e7730f4d21f6f8ebc60f0698404ac31" (ACPI: Remove side effect
of partly creating a node in acpi_map_pxm_to_online_node) by
Jonathan Cameron. When the system does not support NUMA architecture,
the "socket_id" is expected to be -1. The valid "socket_id" in
BOND PMD is greater than or equal to zero. So it will cause an error
when DPDK checks the validity of the "socket_id" when starting the
bond. This commit can fix this bug.

Fixes: f294e04851fd ("net/bonding: fix socket ID check")
