enum.c: remove volatile, use RB_GC_GUARD

Browse source 
volatile appears unnecessary in most cases as the VALUEs are used as
arguments of uninlined functions.  Even worse, volatile can be
insufficient in places where RB_GC_GUARD is necessary.

* enum.c (zip_ary): remove volatile, use RB_GC_GUARD
  (zip_i): ditto
