BUG/MINOR: server: incorrect report for tracking servers leaving drain
Report message for tracking servers completely leaving drain is wrong:
The check for "leaving drain .. via" never evaluates because the
condition !(s->next_admin & SRV_ADMF_FDRAIN) is always true in the
current block which is guarded by !(s->next_admin & SRV_ADMF_DRAIN).
For tracking servers that leave inherited drain mode, this results in the
following message being emitted:
"Server x/b is UP (leaving forced drain)"
Instead of:
"Server x/b is UP (leaving drain) via x/a"
To this fix: we check if FDRAIN is currently set, else it means that the
drain status is inherited from the tracked server (IDRAIN)
This regression was introduced with 64cc49cf ("MAJOR: servers: propagate server
status changes asynchronously."), thus it may be backported to every stable
versions.
