LU-7653 lod: fix stripe allocation during recovery

replay-single 110f fails sometimes because it gets
less directory stripes during replay. lod_prep_md_striped_create()
skips MDT from allocation if MDT is not connected(dt_statfs returns
error).

lod_prep_md_striped_create()) try idx 0, mdt cnt 2, allocated 1
osp_statfs())Process entered
osp_statfs())Process leaving (rc=18446744073709551509 :
	 -107 : ffffffffffffff95)
lod_prep_md_striped_create())lustre-MDT0001-mdtlov:
	require stripes 2 only get 1

The patch allows striping if lod target is active(fid allocation
is working).
