    libpcp events support - fix error code
    
    malloc and PoolAlloc cleanup code for nested or bad event types was
    (always?) broken.
    QA 404/405 exposed this, not sure how it escaped notice and
    detection up to now.
    Error is in extremely unlikely error branch for normal use, which
    helps explain why no one else has reported it.
