Inference with a grammar was sometimes generating null characters, effectively causing the output to hang. Probably introduced in #2553. It turns out
llama_sample_grammarwasn't accounting for the'\0'token. This patch fixes the issue by rejecting that token unconditionally, treating it the same way as empty tokens.
