[Nbd] nbd-client zombies

[Michal Belczyk <belczyk@...1274...>]

Hello,

could you please add some code to nbd-client to prevent zombie processes
to show up once it is started?
The following patch fixes it for me but I do not mind calling wait() or
any other way to fix it properly (your way)... mine is just a quick
hack...

Thank you!
