[U-Boot] [PATCH 7/7] GCC4.6: Squash warning in cmd_mem.c

cmd_mem.c: In function ?do_mem_loop?:
cmd_mem.c:474:25: warning: variable ?junk? set but not used
[-Wunused-but-set-variable]

The assigned variable can be removed because the pointers are volatile so
accesses to their addresses are always generated.
