block-backend: Update ctx immediately after root
blk_get_aio_context() asserts that blk->ctx is always equal to the root
BDS's context (if there is a root BDS). Therefore,
blk_do_set_aio_context() must update blk->ctx immediately after the root
BDS's context has changed.
Without this patch, the next patch would break iotest 238, because
bdrv_drained_begin() (called by blk_do_set_aio_context()) may then
invoke bdrv_child_get_parent_aio_context() on the root child, i.e.
blk_get_aio_context(). However, by this point, blk->ctx would not have
been updated and thus differ from the root node's context. This patch
fixes that.
