Hi,
This series has changes to reset the queue/io_timeout for nbd devices and
a cleanup patch.
Thank you!

Without any changes to NBD_ATTR_TIMEOUT (default is 30 secs),
$ rbd-nbd map rbd-pool/image0 --try-netlink
/dev/nbd0
$ cat /sys/block/nbd0/queue/io_timeout
30000
$ rbd-nbd unmap /dev/nbd0
$ cat /sys/block/nbd0/queue/io_timeout
30000
Now user sets NBD_ATTR_TIMEOUT to 60,
$ rbd-nbd map rbd-pool/image0 --try-netlink --io-timeout 60
/dev/nbd0
$ cat /sys/block/nbd0/queue/io_timeout
60000
$ rbd-nbd unmap /dev/nbd0
$ cat /sys/block/nbd0/queue/io_timeout
60000
Now user doesn't alter NBD_ATTR_TIMEOUT, but sysfs still shows it as 60,
$ rbd-nbd map rbd-pool/image0 --try-netlink
/dev/nbd0
$ cat /sys/block/nbd0/queue/io_timeout
60000
$ rbd-nbd unmap /dev/nbd0
$ cat /sys/block/nbd0/queue/io_timeout
60000
The problem exists with ioctl interface too.
