any errors in zfs_set_prop_nvlist needs reverting the changes done here.. instead, this can be called if no errors after performing zfs_set_prop_nvlist..

lets make the fn name as 'uzfs_zinfo_set_prop' as this performs setting few flags on zinfo as well in case of readonly flag..

calling function that can set all properties will make those variables get set in zinfo / zv.. for ex., zvol_workers will be set in zv, but, it won't get impacted until zrepl restarts..
So, instead of calling function saying uzfs_zinfo_set_prop, how about setting only for uzfs_zinfo_set_readonly if prop is READONLY

@vishnuitta @mynktl , io.openebs:readonly does not convey it's meaning, also it conflicts with the existing readony property. Can we rename it to io.openebs:suspend (or some better name)?

both property have the same functionality but at different layer. To differentiate this i thought of giving a different name. One more point, this is completely limited to cstor API layer only, so better to group it with organization.

lets allow setting both (targetip and readonly) at once if we want to?

we can do that, but that will complicate creation part i think from control plane, need to check. We can plan this in next release.

what is the problem if we remove 'else' which allows both the settings?
