Fix jumping progress bar. (#11439)

Browse source 
- When LCD_SET_PROGRESS_MANUALLY was disabled and an SD print was not active (i.e. the printer was idle), progress_bar_percent would read uninitialized memory from stack and cause progress bar to jump wildly.
- Also updated conditions in `#ifdef` to match `ultralcd.cpp`
