checkpatch: Allow spaces after all coroutine annotations

The coroutine annotations may be used in the declaration of function pointers, which triggers checkpatch due to the space before the parentheses. E.g: int coroutine_fn (*run)(Job *job, Error **errp); ^ The coroutine_fn annotation is already included in the list of terms where spaces are allowed. Add the other coroutine annotations: coroutine_mixed_fn and no_coroutine_fn.
