mac80211_hwsim uses HRTIMER_MODE_ABS_SOFT and HRTIMER_MODE_REL_SOFT now.
These enum entries were added in commit 98ecadd4305d ("hrtimer: Add
clock bases and hrtimer mode for softirq context") in kernel 4.16.
This will execute the timers in hard interrupt context and not in soft
interrupt context like intended.
