Fix Lint error

Error:
========================================================================
[NewApi] Field requires API level 35 (current min is 33):
REGISTER_NSD_OFFLOAD_ENGINE

+ String.join(", ", List.of(REGISTER_NSD_OFFLOAD_ENGINE, NETWORK_STACK,
========================================================================

1. The REGISTER_NSD_OFFLOAD_ENGINE is only available on API level 35.
2. The error message in the exception is incorrect. It should be 3
   cases: V+, U, others.
3. Fix this Lint error because it will block aosp/2832130 merge.
