[dpdk-stable] [PATCH] tools: fix active interface detection in dpdk-devbind.py

[Yoni Gilad <yonig@radcom.com>]

When adding crypto devices, the "Active" and "Ssh_if" attributes of
existing network devices were reset. This causes the follwing issues:

- Network interfaces aren't marked as "*Active*" in the --status output.
- Active network interfaces can be unbound without the --force option,
  causing loss of network connection.

The reset was caused by the call to devices[d].update in
get_crypto_details.

This patch prevents the update on non-crypto devices.

Fixes: cb4a1d1 ("tools: bind crypto devices")
