Make "set/show remoteaddresssize" a zuinteger command instead of uinteger. 

It makes no sense to talk about an "unlimited" address size in this
context.

 (gdb) show remoteaddresssize
 The maximum size of the address (in bits) in a memory packet is 0.
 (gdb) set remoteaddresssize 0
 (gdb) show remoteaddresssize
 The maximum size of the address (in bits) in a memory packet is unlimited.

"set remoteaddresssize 0" mapping to UINT_MAX means you can't
force gdb through this path twice in the same GDB run:

  static CORE_ADDR
  remote_address_masked (CORE_ADDR addr)
  {
    unsigned int address_size = remote_address_size;

    /* If "remoteaddresssize" was not set, default to target address size.  */
    if (!address_size)
      address_size = gdbarch_addr_bit (target_gdbarch ());
