block-backend: simplify blk_get_aio_context 

blk_get_aio_context verifies if BlockDriverState bs is not NULL,
return bdrv_get_aio_context(bs) if true or qemu_get_aio_context()
otherwise. However, bdrv_get_aio_context from block.c already does
this verification itself, also returning qemu_get_aio_context()
if bs is NULL:

AioContext *bdrv_get_aio_context(BlockDriverState *bs)
{
    return bs ? bs->aio_context : qemu_get_aio_context();
}

This patch simplifies blk_get_aio_context to simply call
bdrv_get_aio_context instead of replicating the same logic.
