leds: pca963: fix misleading indentation

I'm getting warnings:

/tmp/next/build/drivers/leds/leds-pca963x.c: In function 'pca963x_register_leds':
/tmp/next/build/drivers/leds/leds-pca963x.c:355:3: error: this 'if' clause does not guard...

  357 |    led->blinking = false;
      |    ^~~
cc1: all warnings being treated as errors

Fix the indentation to make them go away.
