Nav modes momentarily zeroing throttle when decreasing altitude on MR

[avsaase]

When the quad reaches the home position in RTH and it starts the landing sequence, I noticed it momentarily pulls the throttle almost to zero before landing as normal. The same happens in POS HOLD when commanding an altitude decrease. The throttle decrease is clearly audible when standing nearby, and shows on the OSD and the blackbox log.

• FC Board name and vendor: Kakute F7 mini V3
• INAV version string: INAV/KAKUTEF7MINIV3 2.6.0 Feb 26 2021 / 15:58:49 (518fa1e9) This is a custom 2.7 build (that pretends to be 2.6 for SpeedyBee app compatibility) with some of my PR's that were merged yesterday, as well as Add OSD Stats pages and some crsf formatting fixes #6598 and Fix Nav Launch detection related bugs #6430. None have anything to do with throttle behavior. If this is not reproducible I can try with stock 2.6.1.
