iio:light:tsl2563: Replace cancel_delayed_work() with cancel_delayed_work_sync().
Since cancel_delayed_work(&chip->poweroff_work) does not guarantee that
tsl2563_poweroff_work() is not running, tsl2563_set_power(chip, 0) can be
called from tsl2563_poweroff_work() after tsl2563_get_power(chip) and
tsl2563_set_power(chip, 1) are called. Use _sync version in order to make
sure that tsl2563_poweroff_work() is no longer running.
