nfp: flow_offload: move flow_indr_dev_register from app init to app start

In commit 74fc4f828769 ("net: Fix offloading indirect devices dependency
on qdisc order creation"), it adds a process to trigger the callback to
setup the bo callback when the driver regists a callback.

In our current implement, we are not ready to run the callback when nfp
call the function flow_indr_dev_register, then there will be error
message as:

So we need to call flow_indr_dev_register in app start process instead of
init stage.
