nbd: don't set the device size until we're connected
A user reported a regression with using the normal ioctl interface on newer kernels. This happens because I was setting the device size before the device was actually connected, which caused us to error out and close everything down. This didn't happen on netlink because we hold the device lock the whole time we're setting things up, but we don't do that for the ioctl path. This fixes the problem.
