ui: Only set brightness when needed.

There is a regression due to recent change in commit
b76af93ab56bc3296e01e65a6fe64a0622ab5b91, where it started to set
brightness to normal on every key input. This is unneeded and spamming
the recovery log.

Test: Run recovery_unit_test on marlin.
Test: Built and boot into recovery image. Press a few keys, then check
      the recovery log.
