LU-11024 osd-zfs: properly detect ZFS dnode accounting

Properly detect if native ZFS dnode accounting is available for
ZFS 0.7.x releases that do not contain ZFS project quota.  The
function signature changed after ZFS Project Quota was landed,
but we still need to check for the old function for 0.7.x.
