LU-11549 mdd: set LUSTRE_ORPHAN_FL for non-dirs

LU-11549 mdd: set LUSTRE_ORPHAN_FL for non-dirs

mdd_mark_orphan_object() sets LUSTRE_ORPHAN_FL only for
directories, which is not correct, causing the important bit of
orphan object state not transferring across OSP link and
allowing a distributed link operation to succeed
for an orphan source object , causing a dangling reference
on one mdt and an unconnected inode on another mdt.
mdd_open_sanity_check() conditions had to be relaxed in
case of replay.
