NativeSurface.unlockSurface(): Change fail-fast policy to fail safe tolerant

- This policy allows more simple destruction handling w/o validating on the top level.

- Hence 'unlockSurface()' shall not throw any exception.

- 'lockSurface()' keeps unchanges, clarified w/ explicit 'throws' declaration,
  ie will fail-fast.
