i386: Fix a pasto in ix86_expand_int_sse_cmp [PR114339]

In r13-3803-gfa271afb58 I've added an optimization for LE/LEU/GE/GEU
comparison against CONST_VECTOR.  As the comments say:
         /* x <= cst can be handled as x < cst + 1 unless there is
            wrap around in cst + 1.  */
...
                     /* For LE punt if some element is signed maximum.  */
...
                 /* For LEU punt if some element is unsigned maximum.  */
and
         /* x >= cst can be handled as x > cst - 1 unless there is
            wrap around in cst - 1.  */
...
                     /* For GE punt if some element is signed minimum.  */
...
                 /* For GEU punt if some element is zero.  */
Apparently I wrote the GE/GEU (second case) first and then
copied/adjusted it for LE/LEU, most of the adjustments look correct, but
I've left if (code == GE) comparison when testing if it should punt for
signed maximum.  That condition is never true, because this is in
switch (code) { ... case LE: case LEU: block and we really meant to
be what the comment says, for LE punt if some element is signed maximum,
as then cst + 1 wraps around.

The following patch fixes the pasto.
