Let the free running port state reflect the synchronization uncertain flag. 

When using the "free running" option, a slaved port remains in the
UNCALIBRATED state.  If the actual servo resides in and external program,
for example when following the 802.1AS recommendations, that program can
signal the synchronization state using the "synchronization uncertain"
management message. This patch lets the port state transitions from
UNCALIBRATED to SLAVE based on that message.
