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.
