Bug#30822: ALTER TABLE COALESCE PARTITION causes segmentation fault

Browse Source 
Problem was for LINEAR HASH/KEY. Crashes because of wrong partition id
returned when creating the new altered partitions. (because of wrong
linear hash mask)

Solution: Update the linear hash mask before using it for the new
altered table.
