bug #24502 (reorganize partition closes connection)

Browse Source 
when REORGANIZE creates new partition, no_subparts for that partition
isn't set right (call handler::set_partitions_defaults always returns 1)
Normally the number of subpartitions should be inherited from the
table.


mysql-test/r/partition.result:
  result fixed
mysql-test/t/partition.test:
  testcase
sql/sql_partition.cc:
  no_subparts is set for newly created partitions
