Revert "SUNRPC: Micro-optimise when the task is known not to be sleeping"

This reverts commit ec497e55040db925c488a717bdcdcf590c7b8f8e.

The ability to optimise here relies on compiler being able to optimise
away tail calls to avoid stack overflows. Unfortunately, we are seeing
reports of problems, so let's just revert.
