Avoid useless calls in pg_get_multixact_stats()
MultiXactOffsetStorageSize() and GetMultiXactInfo() are called to gather
the information reported by the function, but were wasteful for the case
where a role does not have the privileges of pg_read_all_stats, where we
return a set of NULLs. These calls are moved to the code path where
their results are used.
