Eric R. Smith 5236fb1683 pan: fix a bifrost disassembly assert failure
We were overflowing an array during bifrost disassembly. This was
only a problem if the user explicitly set an environment variable,
so unlikely to occur in casual use, and also only could be triggered
in very specific, dense code. But we still should get this right!

The specific CTS test that caused the assert is:

'dEQP-VK.graphicsfuzz.stable-quicksort-for-loop-with-injection'

with environment variable `BIFROST_MESA_DEBUG=shaders`. One of the
shaders has a clause with 6 constants (the maximum) and this overflowed
the array because we assume we always have an extra slot (used for
modifier processing).
