LU-1864 osd-zfs: Use the correct lu_site in arc_prune_func()

arc_prune_func() purges osd_device::od_site.  While this is correct on
orion and master, b2_3 does not initialize or use osd_device::od_site
at all.  This patch changes arc_prune_func() to use the correct
lu_site from osd_device::...::ld_site, which points to
ofd_device::ofd_site.
