[ALSA] system timer: fix lost ticks correction adjustment
Fix the adjustment of the lost ticks correction variable in the case when the correction has been fully taken into account in the next timer expiration value. Subtracting the scheduled ticks value would result in an underflow. Signed-off-by: Clemens Ladisch <clemens@ladisch.de> Signed-off-by: Jaroslav Kysela <perex@suse.cz>
