leds: don't disable blinking when writing the same value to delay_on or delay_off
Function led_set_software_blink() assumes that blink timer is still running, but commit 488bc35bf40df89d37486c1826b178a2fba36ce7 introduced disabling of blink timer before each call to led_set_software_blink(). Correct led_software_blink(): 1) remove protection against reprogramming blink timer to the same values, because it only disables blinking now, 2) remove unnecessary call to led_stop_software_blink().
