Zeb Hering 86f3b0c323 Enforce that full cooling arrives no later than the disk alarm ...

DISK_RAMP_HIGH_OFFSET below DISK_ALARM_OFFSET means the alarm fires
while there is still cooling left unused. iz-pve0 was tuned that way by
hand (full at limit-2, alarm at limit-5), which would have mailed 3c
before the fans were actually flat out, for every drive class.

check_ramp_ordering() now clamps at startup and logs it, rather than
exiting - a fan controller that refuses to start leaves the fans
wherever they were.
