Fixes a compilation warning:
passing argument 2 of ‘apply_param_change’ discards ‘const’ qualifier from pointer target type

Since the PVQ search has been well fuzzed and is guaranteed to never
break SUM(abs(y[])) == K, the assert is no longer needed.
Also the assert only prevented coding the wrong vector index but didn't
prevent crashes during searching for it, which made the assert rather
informational than practical.

Since the probelm mentioned only happened when the phase was negative
(e.g. the sum had to be decreased), only discarding dimensions with a
zero pulse in that case restored the search's previously low distortion
at low Ks when the phase is never negative.
