HBASE-25835 Ignore duplicate split requests from regionserver reports (#3218)

Processing of the RS report happens asynchronously from other activities
which can mutate region state. For example, a split procedure may already
be running. A split procedure cannot succeed if the parent region is no
longer open, so we can ignore it in that case.

Note that submitting more than one split procedure for a given region is
harmless -- the split is fenced in the procedure handling -- but it would
be noisy in the logs. Only one procedure can succeed. The other
procedure(s) would abort during initialization and report failure with
WARN level logging.
