leds: lm3692x: Fix regulator/gpio leak and wrong enabled state on last write failure

Browse Source 
Every write in lm3692x_leds_enable() checks its return and jumps to
out: on failure -- except the last one, which falls through and sets
led->enabled = true regardless of whether it actually succeeded. Leaks
the regulator on a failing probe, and short-circuits later
brightness_set() calls without retrying.

Route it through out: like every other write here, and only set
enabled = true once it succeeds.
