[BUG] Unsafe behavior on mesh generation and bltouch probing error

[thephantom1492]

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

Yes, and the problem still exists.

Bug Description

I had a small misconfiguration that exposed the bug. #define Z_CLEARANCE_DEPLOY_PROBE 5 This cause the bltouch to not be able to deploy during probing for the mesh.

Bug Timeline

Atleast since git of 2023-05-24

Expected behavior

Going into stop/panic as to prevent damage from whatever caused the probe to not deploy.

Actual behavior

A message about probing error and stop and to issue M999 to resume, but it continue to probe. Sorry I forgot to save the exact message before fixing the config.

Steps to Reproduce

Set #define Z_CLEARANCE_DEPLOY_PROBE 10 Or Have a faulty bltouch

Issue: G29 P1 Watch as the probe fail to deploy, a message get spammed in the terminal about the error, a message is spammed about stop and to M999
