Fix corne keylog (#22420)

* [Keyboard] Fix bug in set_keylog function

Fixes issue where some keys would not trigger the oled to output the row
and column of a pressed key (would happen with LT(...) for my keymap)

* [Keyboard] Tiny improvement to oled_render_keylog for crkbd

Added improvement suggestion I got for another keyboard
