optimisation: simplify two LCD messages

There is no need to restrict how often the message is rendered.
It was being restricted to render every 1 second. We don't do
this for most of the static menus. So I propose this 1 second period
be removed.

Tested on MK3S+

Change in memory:
Flash: -168 bytes
SRAM: -8 bytes
