Subject: [PATCH net-next] net: include <linux/hex.h> from sysctl_net_core.c

Needed for hex_byte_pack().

x86_64 was already including it, but some arches were not.

Fixes: 37b0ea8fef56 ("net: expand NETDEV_RSS_KEY_LEN to 256 bytes")
Reported-by: Mark Brown <broonie@...nel.org>
Closes: https://lore.kernel.org/netdev/aXeka0KYBnrkwUcF@sirena.org.uk/
