Fix notifications count change during animation on keyguard

max keyguard displayed notifications was being updated while an animation was in progress, getting a wrong top padding (as all the views were translated upwards during the hint animation).
The update is skipped in this case.

Fixes: 220800339
Fixes: 228170071
Test: add notifications, trigger hint and aod animation => notification count is not updated in the middle
