nbd: add set flags ioctl
Add a set-flags ioctl, allowing various option flags to be set on an nbd
device. This allows the nbd-client to set the device flags (to enable
read-only mode, or enable discard support, etc.).
Flags are typically specified by the nbd-server. During the negotiation
phase of the nbd connection, the server sends its flags to the client.
The client then uses NBD_SET_FLAGS to inform the kernel of the options.
Also included is a one-line fix to debug output for the set-timeout ioctl.
