75da15eccc devmapper: Call UdevWait() even in failure path 
Currently we set up a cookie and upon failure not call UdevWait(). This
does not cleanup the cookie and associated semaphore and system will
soon max out on total number of semaphores.

To avoid this, call UdevWait() even in failure path which in turn will
cleanup associated semaphore.

3b01a00fa3 devmapper: use proper DM_UDEV_DISABLE_*_FLAG when creating the thin-pool 
Otherwise udev can unecessarily execute various rules (and issue
scanning IO, etc) against the thin-pool -- which can never be a
top-level device.
