Revert "device: restart DHCP when the MAC changes"

The commit causes problems with bridges. When a new port is attached
the MAC of the bridge possibly changes and if we restart DHCP the
bridge will get a different IP address.

Revert the change until a better solution to the original problem is
found.

This reverts commit 905adabdba.
