[BUG] M117 doesn't work with Stowable Z-PROBE

[jgilmore]

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

Yes, and the problem still exists.

Bug Description

With the following settings:
#define FIX_MOUNTED_PROBE
#define PAUSE_BEFORE_DEPLOY_STOW

When told to home, (Marlin will pause and display a "Deploy Z-Probe" message, and a "Stow Z-Probe" message afterward. This is correct behavior.

What is NOT correct, is that the "Stow Z-Probe" message is then permanently displayed. All sorts of errors that REALLY REALLY SHOULD display a message (like wait-for-temperature timeout, temperature out of range, etc.) don't, and instead display the "Stow Z-Probe" message.

This makes it rather difficult to determine why the print stopped and the printer is now beeping for all it's worth! Hiding error messages is a big deal.

The M117 messages also don't display. (I have one before each layer in the G-code, so I can tell how far along it is.)

Please note that while this is an older firmware version, this bug is kinda corner case (only affecting manually stowable Z-probe printers) and I would be surprised if it doesn't still exist in latest. I would test this, but I'm in the middle of a 21-hour (predicted) print. (Thus having time to type this up.)

Expected behavior

Your provided configs shows CONFIGURATION_H_VERSION 02000902
This is positively ancient code

Please test the bugfix-2.1.x branch to see where it stands. If the problem has been resolved then we can close this issue. If the issue isn't resolved yet, then we should investigate further.

This issue still occurs with latest bugfix-2.1.x branch, been meaning to look into this for ages but just lived with it.
Hopefully just a one line fix unless I am missing something.
