Bug#40389: REORGANIZE PARTITION crashes when only using one partition

Browse Source 
The non documented command 'ALTER PARTITION t REORGANIZE PARTITION'
(without any partitions!) which only make sense for nativly
partitioned engines, such as NDB, crashes the server if there was
no change of number of partitions.

The problem was wrong usage of fast_end_partition function,
which led to usage of a non initialized variable.
