Willy Tarreau 9b46fb4cca BUG/MINOR: server: do not enable DNS resolution on disabled proxies
Leonhard Wimmer reported an interesting bug in github issue #1742.
Servers in disabled proxies that are configured for resolution are still
subscribed to DNS resolutions, but the LB algos are not initialized at
all since the proxy is disabled, so when the server state changes,
attempts to update its status cause a crash when the server's weight
is recalculated via a divide by the proxy's total weight which is zero.

This should be backported to all versions. Beware that before 2.5 or
so, there's no PR_FL_DISABLED flag, instead px->disabled should be
used (2.3-2.4) or PR_STSTOPPED for older versions.

Thanks to Leonhard for his report and quick test!
