array.c: fix array size
* array.c (rb_ary_permutation): `p` is the array of size `r`, as commented at permute0(). since `n >= r` here, buffer overflow never happened, just reduce unnecessary allocation though. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@46416 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
