[BUG] Cold extrude not saved during Power Panic

[wavexx]

Printer type - MK2.5+
Printer firmware version - 3.9+
MMU Upgrade - N/A
SD card or USB/Octoprint - N/A

Describe the bug
A print started using the cold extrude feature (M302) will fail to resume printing after a power-panic, since the limit temperature is not saved.

To Reproduce
Start a print with cold-extrusion (any temp below 175):

M302 S150
M104 S150

Trigger PP. As soon as extrusion is started the printer will stop due to cold extrusion prevention.

Expected behavior
Printer should continue printing as usual.

This is unlikely to cause significant issues, since the current cold-extrusion limit is pretty low.
