Remove "recheck" argument from check_index_is_clusterable()

Browse Source 
The last usage of this argument in this routine can be tracked down to
7e2f9062, aka 11 years ago.  Getting rid of this argument can also be an
advantage for extensions calling check_index_is_clusterable(), as it
removes any need to worry about the meaning of what a recheck would be
at this level.
