[BUG] (bug summary) BILINEAR bug with Endstop homing and Probe installed

[12oclocker]

Did you test the latest bugfix-2.1.x code?

Yes, and the problem still exists.

Bug Description

If using a machine with Z endstop homing, and probe only for leveling, (USE_PROBE_FOR_Z_HOMING is DISABLED), AUTO_BED_LEVELING_BILINEAR enabled, and ENABLE_LEVELING_AFTER_G28 enabled. After setting Z Probe Offset and saving to EEPROM, the machine must be power cycled before creating bed leveling mesh. Otherwise the mesh does not subtract the Z probe offset during creation.
I believe all of these bug reports are related to this issue...

Expected behavior

we expect the machine to not need power cycled before creating a bed leveling mesh.

Actual behavior

bed leveling mesh creation does not subtract z probe offset unless machine is power cycled after changing Z probe offset.

, then go to "edit mesh" menu and see mesh was created wrong (Z Probe Offset not subtracted)
