sft freeing attempt made in a575421 ("BUG/MINOR: sink: missing sft free in
sink_deinit()") is incomplete, because sink->sft is meant to be used as a
list and not a single sft entry.
Because of that, the previous fix only frees the first sft entry, which
fixes memory leaks for single-server forwarders (this is the case for
implicit rings), but could still result in memory leaks when multiple
servers are configured in a explicit ring sections.
What this patch does: instead of directly freeing sink->sft, it iterates
over every list members to free them.
It must be backported up to 2.4 with a575421.
