If a "ring" section initialization fails (e.g. due to a duplicate name,
invalid chars, or missing memory), any subsequent "server" statement that
appears in the same section will crash the config parser by dereferencing
the currently NULL cfg_sink. E.g:
ring x
ring x # fails on "already exists"
server srv 1.1.1.1 # crashes on cfg_sink==NULL
All other statements have a test for this but "server" was missing it,
so this patch adds it.
Thanks to Joel Hutchinson for reporting this issue.
This must be backported as far as 2.2.
