block-backend: process I/O in the current AioContext
Switch blk_aio_*() APIs over to multi-queue by using qemu_get_current_aio_context() instead of blk_get_aio_context(). This change will allow devices to process I/O in multiple IOThreads in the future. I audited existing blk_aio_*() callers: - migration/block.c: blk_mig_lock() protects the data accessed by the completion callback. - The remaining emulated devices and exports run with qemu_get_aio_context() == blk_get_aio_context().
