greybus: timesync: Bugfix ping should not result in -EAGAIN

Browse source

gb_timesync_schedule_synchronous() is currently making a synchronous
FrameTime synchronization happen. It does a wait_event_interruptible() and
then goes to check the status of the state-machine. Occasionally the state
indicates PING - which is a completely valid state and should result in a
result code of 0 not -EAGAIN. This patch fixes by making
__gb_timesync_get_status() return 0 instead of -EAGAIN for the PING state.
