core/state: commit snapshot only if the base layer exists (#30493)

Browse Source 
This pull request skips the state snapshot update if the base layer is
not existent, eliminating the numerous warning logs after an unclean
shutdown.

Specifically, Geth will rewind its chain head to a historical block
after unclean shutdown and state snapshot will be remained as unchanged
waiting for recovery. During this period of time, the snapshot is unusable
and all state updates should be ignored/skipped for state snapshot update.
