alarmtimer: Return correct remaining time
commit 07d7e12091f4ab869cc6a4bb276399057e73b0b3 upstream.
To calculate a remaining time, it's required to subtract the current time
from the expiration time. In alarm_timer_remaining() the arguments of
ktime_sub are swapped.
Fixes: d653d8457c76 ("alarmtimer: Implement remaining callback")
