BUG/MINOR: backend: nbsrv() should return 0 if backend is disabled

According to nbsrv() documentation this fetcher should return "an
integer value corresponding to the number of usable servers".
In case backend is disabled none of servers is usable, so I believe
fetcher should return 0.

This patch should be backported to 1.7, 1.6, 1.5.
