[http] Notify data transfer interface when underlying connection is ready
HTTP implements xfer_window_changed() on the underlying server
connection using http_step(), which does not propagate the window
change notification to the data transfer interface. This breaks the
multipath-capable SAN boot code, which relies on the window change
notification to discover that the HTTP block device is ready for
commands to be issued.
Fix by sending xfer_window_changed() in http_step() once the
underlying connection has been determined to be ready.
