Stefan Hajnoczi 365911b182 qemu-io: add cvtnum() error handling for zone commands ...

cvtnum() parses positive int64_t values and returns a negative errno on
failure. Print errors and return early when cvtnum() fails.

While we're at it, also reject nr_zones values greater or equal to 2^32
since they cannot be represented.
