[PATCH] leds: ledtrig-pattern: Use last_repeat when applying hw pattern

[Marijn Suijten <marijn.suijten@somainline.org>]

`last_repeat` holds the actual value requested by the user whereas
`repeat` is a software iteration variable that is unused in hardware
patterns.

Furthermore `last_repeat` is the field returned to the user when reading
the `repeat` sysfs property.  This field is initialized to `-1` which is
- together with `1` - the only valid value in the upcoming Qualcomm LPG
driver.  It is thus unexpected when `repeat` with an initialization
value of `0` is passed into the the driver, when the sysfs property
clearly presents a value of `-1`.
