This patch addresses the bug observed in ptp4l in slaveOnly mode. When the
upstream master is no longer available (not reachable), the slave moves to
LISTENING state. However, the gmIdentity is not updated in ptp4l. This causes
gmPresent reported as true despite GM being non-reachable in pmc commands.
