From: Jiri Pirko <jiri@nvidia.com>

The existing setup_wait*() helper family check the status of the
interface to be up. Introduce wait_for_dev() to wait for the netdevice
to appear, for example after test script does manual device bind.

v3->v4:
- removed "up" from ip link command line
v1->v2:
- reworked wait_for_dev() helper to use slowwait() helper
