[dhcp] Allow for links that remained blocked for up to three minutes

With the default timeouts for Cisco MAC Authentication Bypass, the
link will remain blocked for around 90 seconds (plus a likely
subsequent delay for STP).

Extend the maximum number of DHCP discovery deferrals to allow for up
to three minutes of waiting for a link to become unblocked.
