BUG/MEDIUM: httpclient: check if the httpclient was released in the IO handler

Upon a applet_release(), the applet can be scheduled again and a call to
the IO handler is still possible. When the struct httpclient is already
free the IO handler could try to access it.

This patch fixes the issue by setting svcctx to NULL in the
applet_release, and checking its value in the IO handler.

Must be backported as far as 2.5.
