Remove "recheck" argument from check_index_is_clusterable()
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.
