Fixed alter online table for Aria tables

Browse Source 
fill_alter_table() always thought that index was changed because of
of a wrong check of block_size. Some engines had code to correct this
that should not be needed, Aria didn't and because of this some online
operations didn't work.

This code fixes the comparision of block_size to only compare if it's set.
