Handle error from watch.

A watch of the API can return an api.Status rather than the watched
obejct type.  This code didn't handle that.

Tested with services e2e test (in conjunction with other PR).
Proxy: Avoid log error.  Simplify locking.

Don't log an error when Accept failed because the interface (portal)
was just removed.

Don't pass around a pointer to a serviceInfo since another thread
deletes those.  Instead, just check if service name is still in the
service map.

Delete the locking on the serviceInfo object since it is only used
by the "main" proxier thread.
