thread.c (rb_thread_fd_select): remove unnecessary rb_fd_resize calls
There's no need to resize each rb_fdset_t to match the size of the biggest one. This can allow some small memory savings if watching several sets of FDs simultaneously. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@64017 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
