    Fix error when restarting a connection
    
    When restarting a connection with busterminate() + businit(), the
    message_buffer pointer is NULL but max_message_len wasn't reset to
    0 because it is a static local variable and the test len > max_message_len
    can fail which means a new buffer isn't allocated and a NULL is returned.
