MDEV-22866: Server crashes in ... with not_null_range_scan=onbb-10.3-mdev22866
Starting from 10.3, the optimizer is able to detect that entire outer join
nests are constants (because of "Impossible ON") and remove them (see
mark_join_nest_as_const)
However, this was not properly accounted for in NESTED_JOIN structure
and the way check_interleaving_with_nj() uses its n_tables member to
check if the join prefix order is allowed.
(The result was that the optimizer could conclude that no join prefix is
allowed and fail an assertion)
