Bug Report

await-not-async does not warn on async for in list and dict comprehensions, and incorrectly does give a warning for await inside GeneratorExp.elt.
For list & dict comprehensions you should error on any await or async for, but for generator expressions it's only the generator that should be checked.

To Reproduce

def foo(): ... def should_not_error(): (await x for x in foo()) def should_error(): [x async for x in foo()] {k: v async for k, v in foo()} def correctly_errors(): (x for x in await foo()) [await x for x in foo()] def correctly_does_not_error(): (x async for x in foo())

Expected Behavior

It should error on 8, 9, 12 and 13

Actual Behavior

$ mypy foofoo.py foofoo.py:5: error: "await" outside coroutine ("async def") [await-not-async] foofoo.py:12: error: "await" outside coroutine ("async def") [await-not-async] foofoo.py:13: error: "await" outside coroutine ("async def") [await-not-async] Found 3 errors in 1 file (checked 1 source file)
