net: dsa: Fix load order between DSA drivers and taggers
The DSA core, DSA taggers and DSA drivers all make use of module_init(). Hence they get initialised at device_initcall() time. The ordering is non-deterministic. It can be a DSA driver is bound to a device before the needed tag driver has been initialised, resulting in the message: No tagger for this switch Rather than have this be fatal, return -EPROBE_DEFER so that it is tried again later once all the needed drivers have been loaded.
