Bug #41945 cluster reorg part on single partition segv in mysqld

Description:
start a mysqld and a single ndb node cluster...

create table t1 (a int key) engine ndb;
alter table t1 reorganize partition;

...segv

core shows some issue when trying to create the temporary frm file... getting confused with having a single (== no partition)... etc.

How to repeat:
see above

seems to be related to bug#36591 (get_no_parts() call before table is opened).

this is first a duplicate of bug#40389
but after mattias fix for this,
the testcase does *still* not work on ndb,
and we instead get the error message "ERROR 1031 (HY000): Table storage engine for 't1' doesn't have this option"

After mattias "fix" mysql_alter_table will return in 
fast_alter_partition_table and not continue in general online alter table
hence not calling any more ndb functions

      Bug#41945: cluster reorg part on single partition segv in mysqld
      refix of
      Bug #40389: REORGANIZE PARTITION crashes when only using one partition
      
      Problem was a remaining partition info struct that was not cleared,
      resulting in an inconsitent .frm-file
      
      Solution was to only allow REORGANIZE PARTITION on auto partitioned
      native engines, such as NDB, and not trying to do any partitioning
      specific.

for docs:
this is really interesting in 6.4,
but the bug was fixed in 6.2 anyway for easier merging...

Documented bug fix in the NDB-6.2.17, 6.3.23, and 6.4.3 changelogs as follows:

        Executing ALTER TABLE ... REORGANIZE PARTITION on an NDBCLUSTER
        table having only one partition caused mysqld to crash.
