    Destroy ARC buffer in case of fill error
    
    In case of error dmu_buf_fill_done() returns the buffer back into
    DB_UNCACHED state.  Since during transition from DB_UNCACHED into
    DB_FILL state dbuf_noread() allocates an ARC buffer, we must free
    it here, otherwise it will be leaked.
