[media] radio-shark2: Mark shark_resume_leds() inline to kill compiler warning

This mirrors the patch to the radio-shark driver by Geert Uytterhoeven.
If SHARK_USE_LEDS=1, but CONFIG_PM=n:
drivers/media/radio/radio-shark2.c:240: warning: ‘shark_resume_leds’ defined but not used
Instead of making the #ifdef logic even more complicated (there are already
two definitions of shark_resume_leds()), mark shark_resume_leds() inline to
kill the compiler warning. shark_resume_leds() is small and it has only one
caller.
