revert dial and call all

[ale8k]

Description

We ended up creating a duplicate function for dialing all controllers, the only difference was the use of an errgroup. I can see martin wanted to return the first error as he wasn't sure which to return and ultimately for now we've been doing the same thing. Run all the calls, return the first error. As such this reverts and removes that call. It does keep the avoiding db logic still however.
