Use qemu_get_current_aio_context() in mixed wrappers and coroutine wrappers so that code runs in the caller's AioContext instead of moving to the BlockDriverState's AioContext. This change is necessary for the multi-queue block layer where any thread can call into the block layer. Most wrappers are IO_CODE where it's safe to use the current AioContext nowadays. BlockDrivers and the core block layer use their own locks and no longer depend on the AioContext lock for thread-safety. The bdrv_create() wrapper invokes GLOBAL_STATE code. Using the current AioContext is safe because this code is only called with the BQL held from the main loop thread.
