Patch to decide based on symtab_size, not symtab != NULL

The symtab check should go on symtab_size, not whether symtab is allocated.  
In binutils/objdump.c:disassemble_data, sorted_syms is always xmalloc'd, even
if there are no symbols.  The previous patch didn't fix this because *
info->symtab is still (non-NULL) garbage.

Sample output after patching:

...
Sections:
Idx Name          Size      VMA       LMA       File off  Algn
  0 .text         00003710  000080ac  000080ac  000000ac  2**2
                  CONTENTS, ALLOC, LOAD, CODE
...

SYMBOL TABLE:
no symbols



Disassembly of section .text:

000080ac <.text>:
    80ac:       eb000004        bl      0x80c4
