[PATCH] cooker: Shut down the parser in error state

[Richard Purdie <richard.purdie@linuxfoundation.org>]

If the cooker is in an error state, we shouldn't continue to try parsing.
This fixes an issue where an invalid PR server is detected when bitbake
is started and ensures bitbake exits cleanly rather than hanging.
