file-posix: remove incorrect coroutine_fn calls
raw_co_getlength is called by handle_aiocb_write_zeroes, which is not a coroutine
function. This is harmless because raw_co_getlength does not actually suspend,
but in the interest of clarity make it a non-coroutine_fn that is just wrapped
by the coroutine_fn raw_co_getlength. Likewise, check_cache_dropped was only
a coroutine_fn because it called raw_co_getlength, so it can be made non-coroutine
as well.
