From: Bobi Jam <bobijam...@intel.com>

Store inode's fid in cl_setattr_ost() and OSC packs this info on the
wire (via lustre_set_wire_obdo) so that OST can use.

NOTE: currently lu_fid::f_ver and obdo::o_parent_ver are not used on
OFD device, and we use obdo::o_stripe_idx as
filter_fid::ff_parent::f_ver and save it to the device.
