ublk: enhance check for register/unregister io buffer command
The simple check of UBLK_IO_FLAG_OWNED_BY_SRV can avoid incorrect
register/unregister io buffer easily, so check it before calling
starting to register/un-register io buffer.
Also only allow io buffer register/unregister uring_cmd in case of
UBLK_F_SUPPORT_ZERO_COPY.
Also mark argument 'ublk_queue *' of ublk_register_io_buf as const.
