[PATCH] Don't clobber info->mach in gdb_print_insn_mips

Works for me, though I assume that it was put there for a
reason.  Perhaps a better fix is something like:

  if (proc_desc)
    {
      if (pc_is_mips16 (PROC_LOW_ADDR (proc_desc))
        info->mach =  bfd_mach_mips16;
    }
  else
    {
      if (pc_is_mips16 (memaddr))
       info->mach = bfd_mach_mips16;
    }

which would leave info->mach alone unless pc_is_mips16 is true.
