Support the "version" property on volumes via the zfs_prop_get_int() API
As of this commit, volumes do not possess the version property in
any existing OpenZFS implementation. The zpool upgrade code, however,
uses zfs_prop_get_int() to fetch the version property of all children in
a pool. The semantics of the function, however, demand that it only be
used for known valid properties so it returns a garbage value for volumes.
This patch causes the version of a volume to appear to callers using
the zfs_prop_get_int() API to be that of the default ZPL version for
the implementation. In the future, should volumes gain the property,
its actual value will be used.
