io.c: remove obsolete rb_deferr global variable

This was made obsolete by r4190 back in July 2003.  Furthermore,
this existed less than 3 months as it was only introduced in
r3782.

So with absolutely no references to rb_deferr, I doubt any vim
plugin would care anymore.

ChangeLog: fixup indent of my previous commit, oops :X
