Allow async in nosuspend scope

Starting an async function call is actually a synchronous operation,
since the caller is not awaiting on the callee for a return value.

This commit removes the compiler code which generates the error and
updates the relevant test case.

In the presence of CallModifierAsync, the callee is expected to
suspend, so it should not be changed to CallModifierNoSuspend.
