Fix creation of partition descriptor during concurrent detach
When a partition is being detached in concurrent mode, it is possible
for find_inheritance_children_extended() to return that partition in the
list, and immediately after that receive an invalidation message that
sets its relpartbound to NULL just before we read it.  (This can happen
because table_open() reads invalidation messages.)  Currently we raise
an error
  ERROR:  missing relpartbound for relation %u
about the situation, but that's bogus because the table is no longer a
partition, so we shouldn't be complaining about it.  A better reaction
is to retry the find_inheritance_children_extended call to get a new
list, which will no longer have the partition being detached.

Noticed while investigating bug #18377.

Backpatch to 14, where DETACH CONCURRENTLY appeared.
