qjson: Don't crash when input exceeds nesting limit
We limit nesting depth and input size to defend against input
triggering excessive heap or stack memory use (commit 29c75dd
json-streamer: limit the maximum recursion depth and maximum token
count). However, when the nesting limit is exceeded,
parser_context_peek_token()'s assertion fails.
Broken in commit 65c0f1e "json-parser: don't replicate tokens at each
level of recursion".
To reproduce stuff 1025 open braces or brackets into QMP.
Fix by taking the error exit instead of the normal one.
