sfc: don't unregister flow_indr if it was never registered

sfc: don't unregister flow_indr if it was never registered

In efx_init_tc(), move the setting of efx->tc->up after the
 flow_indr_dev_register() call, so that if it fails, efx_fini_tc()
 won't call flow_indr_dev_unregister().

Fixes: 5b2e12d51bd8 ("sfc: bind indirect blocks for TC offload on EF100")
