leds: save the delay values after a successful call to blink_set()
When calling the hardware blinking function implemented by blink_set(),
the delay_on and delay_off values are not preserved across calls.
Fix that and make the "timer" trigger work as expected when hardware
blinking is available.
BEFORE the fix:
$ cd /sys/class/leds/someled
$ echo timer > trigger
$ cat delay_on delay_off
0
0
$ echo 100 > delay_on
$ cat delay_on delay_off
0
0
$ echo 100 > delay_off
$ cat delay_on delay_off
0
0
AFTER the fix:
$ cd /sys/class/leds/someled
$ echo timer > trigger
$ cat delay_on delay_off
0
0
$ echo 100 > delay_on
$ cat delay_on delay_off
100
0
$ echo 100 > delay_off
$ cat delay_on delay_off
100
100
