LU-9442 osp: can't create IDIF fid number > 0xFFFFFFFF

LU-9442 osp: can't create IDIF fid number > 0xFFFFFFFF

fid_is_last_id didn't recognize IDIFes. This caused OST
to allocate new sequence despite of MDT still used
initial FID_SEQ_IDIF. Finally allocation failed with -115
returned from osd_check_lma:
osd_check_lma()) lustre-OST0000-osd: FID [0x100000001:0x0:0x0] != self_fid [0x100000000:0x0:0x0]

Patch has several typical "IDIF" fixes. Also it has lov_objid
fix to store all 48 IDIF bits instead of 32.
Finally it changes union fields order in ost_id.
Before the fix oi_fid.f_seq addressed oi_id instead of oi_seq.
