[PATCH:libXaw 1/2] Correct order of arguments to XawStackFree()

[Alan Coopersmith]

XawStackAlloc() & XawStackFree() are macros to automate the process of
using a fixed size stack buffer for strings smaller than the buffer size,
and allocating/freeing memory for larger strings.

XawStackFree is defined in src/Private.h as taking (pointer, stk_buffer)
and freeing pointer if it's not pointing to the stack buffer.

Most of the calls of this macro get the ordering right, but a couple
got it reversed, passing a stack buffer to free() instead of the
allocated pointer.

Found by the Parfait 0.5.0.1 bug checking tool:

Error: Free memory not allocated dynamically by alloc (CWE 590)
   Free() was called on a pointer 'buf' to the auto variable 'buf'. Free() must only be used on dynamically allocated memory
        at line 2281 of TextAction.c in function 'DoFormatText'.
          'buf' allocated at line 0 as auto variable.
        at line 2296 of TextAction.c in function 'DoFormatText'.
          'buf' allocated at line 0 as auto variable.
