For ecrdsa, there is no reason to advance the initialization to
subsys_init, this is just to make code clean up to have algorithm
initialization uniform with other implementations.

It’s just that I think that in the commit c4741b230597 ("crypto: run
initcalls for generic implementations earlier"), the modification to
ecrdsa happened to be omitted, because from the point of commit time, it
was submitted at the same time as the ecrdsa commits, and it may happen
to be omitted for ecrdsa.
