LU-8300 lfsck: pass LOC_F_NEW when create new object

For lfsck_create_lpf() case, we know that the target object of
'.lustre/lost+found/MDTxxxx' does not exist, need to pass the
lu_object_conf parameter 'LOC_F_NEW' to the lower layer, then
the OSD will not return -115 to the LFSCK if OI files lost.
