[http] Cleanly shut down potentially looped interfaces 

Use intfs_shutdown() and intfs_restart() to cleanly shut down multiple
interfaces that may loop back to the same object.

This fixes a regression introduced by commit daa8ed9 ("[interface]
Provide intf_reinit() to reinitialise nullified interfaces") which
broke the use of HTTP Basic and Digest authentication.
