ice: move devlink port creation/deletion

Commit a286ba73 ("ice: reorder PF/representor devlink
port register/unregister flows") moved the code to create
and destroy the devlink PF port. This was fine, but created
a corner case issue in the case of ice_register_netdev()
failing. In that case, the driver would end up calling
ice_devlink_destroy_pf_port() twice.

Additionally, it makes no sense to tie creation of the devlink
PF port to the creation of the netdev so separate out the
code to create/destroy the devlink PF port from the netdev
code. This makes it a cleaner interface.

Fixes: a286ba73 ("ice: reorder PF/representor devlink port register/unregister flows")
