json-parser: Output the content of invalid keyword

Browse Source 
When input some invalid word 'unknowcmd' through QMP port, qemu outputs
this error message:
  "parse error: invalid keyword `%s'"

This patch makes qemu output the content of invalid keyword, like:

  "parse error: invalid keyword `unknowcmd'"
