Arnaud Porterie a095147db9 Fix panic on devicemapper initialization ...

The ability to save and verify base device UUID (#13896) introduced a
situation where the initialization would panic when removing the device
returns EBUSY.

Functions `verifyBaseDeviceUUID` and `saveBaseDeviceUUID` now take the
lock on the `DeviceSet`, which solves the problem as `removeDevice`
assumes it owns the lock.
