[PATCH 3/3] greybus: svc: clean up link configuration hack at hello

[Johan Hovold]

Commit ee2f2074fdb2 ("greybus: svc: reconfig APBridgeA-Switch link to
handle required load") added a temporary hack which reconfigures the
link at HELLO by abusing the deferred request processing mechanism.

Restructure the HELLO request processing so that the link-configuration
work is queued before creating the debugfs files and add a comment
explaining why it's there.
