[PULL 3/3] block/blkio: Fix inclusion of required headers

[Stefan Hajnoczi]

From: Peter Krempa <pkrempa@redhat.com>

After recent header file inclusion rework the build fails when the blkio
module is enabled:

../block/blkio.c: In function ‘blkio_detach_aio_context’:
../block/blkio.c:321:24: error: implicit declaration of function 
‘bdrv_get_aio_context’; did you mean ‘qemu_get_aio_context’?

Fix it by including 'block/block-io.h' which contains the required
declarations.
