snapshot: add synchronization point

Browse Source 
Synchronize with udev logic before reusing device as snapshot.

This patch tries to fix the problem with udev, where we manage
to 'active' LV for clearing, then we deactivate such device and
active again as member of 'origin&snapshot' tree all in 1 step.

There needs to be a sync point where udev has time to remove all links,
otherwise we race with scans and we may end-up with mysterious 'free'
links in the system pointing to wrong dm names.

This patch tries to fix failing topology cluster tests..
