Another memattr tweak

- Subject: Another memattr tweak
The following patch allows gdb to display upper bounds of memory regions
correctly when the upper bound wraps to zero. A zero upper bound is a
special case that indicates that the memory region extends to the top of
the target's memory space.

* memattr.c (mem_info_command): Print special case of upper bound
as max CORE_ADDR + 1.
