sheepdog: Fix crash in co_read_response()
This fixes a regression introduced in commit 9d456654. aio_co_wake() can only be used to reenter a coroutine that was already previously entered, otherwise co->ctx is uninitialised and we access garbage. Using it immediately after qemu_coroutine_create() like in co_read_response() is wrong and causes segfaults. Replace the call with aio_co_enter(), which gets an explicit AioContext parameter and works even for new coroutines.
