nbd: produce a better error if neither host nor port is passed
Before:
$ qemu-io-old
qemu-io-old> open -r -o file.driver=nbd
qemu-io-old: can't open device (null): Could not open image: Invalid argument
$ ./qemu-io-old
qemu-io-old> open -r -o file.driver=nbd,file.host=foo,file.path=bar
path and host may not be used at the same time.
qemu-io-old: can't open device (null): Could not open image: Invalid argument
After:
$ ./qemu-io
qemu-io> open -r -o file.driver=nbd
one of path and host must be specified.
qemu-io: can't open device (null): Could not open image: Invalid argument
$ ./qemu-io
qemu-io> open -r -o file.driver=nbd,file.host=foo,file.path=bar
path and host may not be used at the same time.
qemu-io: can't open device (null): Could not open image: Invalid argument
Next patch will fix the error propagation.
