BRIN: Handle concurrent desummarization properly
If a page range is desummarized at just the right time concurrently with
an index walk, BRIN would raise an error indicating index corruption.
This is scary and unhelpful; silently returning that the page range is
not summarized is sufficient reaction.
This bug was introduced by commit 975ad4e602ff as additional protection
against a bug whose actual fix was elsewhere. Backpatch equally.
