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

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

[Yoni Gilad]

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")

Typo in "follwing". Also, the fixline SHA should be " cb4a1d14bf3e", the first 6 bytes.
