If a multipath device has a path grouping policy of "group_by_tpg" and
pp->tpg_id wasn't previously set, set need_reload. If the multipath
device hasn't been created yet, need_reload will get cleared when the
device is created. If the multipath device already exists, the path
likely wasn't in the correct pathgroup, since it was unable to set
pp->tpg_id before the paths were grouped.
