MFV/ZoL: `zfs userspace` ignored all unresolved UIDs after the first

zfsonlinux/zfs@88cfff1824

zfs_main: fix `zfs userspace` squashing unresolved entries

The `zfs userspace` squashes all entries with unresolved numeric
values into a single output entry due to the comparsion always
made by the string name which is empty in case of unresolved IDs.

Fix this by falling to a numerical comparison when either one
of string values is not found. This then compares any numerical
values after all with a name resolved.
