From: Johannes Berg <johannes.berg@xxxxxxxxx>
There's either the pldr_sync case, in which case we didn't want
or do the retry loops anyway, or things will just continue to
fail. Remove the retry loop that was added in a previous attempt
to address the issue that was later (though still a bit broken)
addressed by the pldr_sync case.
