rumpdisk: Support opening a device several times
* rumpdisk/block-rump.c (struct block_data): Make taken field an integer
instead of a boolean.
(device_open): When search_bd succeeds, set a new reference and return a
new port right. Separate out io_return_t err, int fd, and int ret to avoid
confusions. Simplify the error handling path.
(device_close): Decrement reference and close rump disk only when
reaching zero. Also destroy our port.
