net: move replay logic to tc_modify_qdisc
Eric reports that by the time we call netdev_lock_ops after
rtnl_unlock/rtnl_lock, the dev might point to an invalid device.
As suggested by Jakub in [0], move rtnl lock/unlock and request_module
outside of qdisc_create. This removes extra complexity with relocking
the netdev.
