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().
