IMPALA-7090: Limit the size of expr created by EqualityDisjunctsToInRule
Currently EqualityDisjunctsToInRule introduced in IMPALA-5280 might
create an expr with unlimited number of children and fails a query,
which should be avoided. The easy solution is to not apply the
rewrite when the number of children is large.
