network scripts: Avoid infinite loop of arping
Introduced in the bonding driver (commit ae46f184bc1f) Driver now reports transmission failures.
Before that, it silently dropped the packet and replied with success error code.
The arping of iputils retries endlessly when a transmission error occurs.
This patch fix this behavior.
Resolves: #1928098
(cherry picked from commit afbd6b5a0aa0873a606cbc99ee418b4de8c3d2dc)
