vkd3d-shader/spirv: Do not reallocate the SPIR-V program.

I ran the compilation of ~1000 DXBC-TPF shaders randomly taken from
my collection and measured the performance using callgrind and the
kcachegrind "cycle count" estimation.

BEFORE:
 * 1,846,641,596 cycles
 * 1,845,635,336 cycles
 * 1,841,335,225 cycles

AFTER:
 * 1,764,035,136 cycles
 * 1,767,948,767 cycles
 * 1,773,927,734 cycles

So callgrind would estimate a 3.6% improvement at least.

The counterpoint is that the caller might get an allocation that
is potentially bigger than necessary. I would expect that allocation
to be rather short-lived anyway, so that's probably not a problem.
