torture: Make torture_hrtimeout_ns() take an hrtimer mode parameter
[ Upstream commit a741deac787f0d2d7068638c067db20af9e63752 ]
The current torture-test sleeps are waiting for a duration, but there
are situations where it is better to wait for an absolute time, for
example, when ending a stutter interval. This commit therefore adds
an hrtimer mode parameter to torture_hrtimeout_ns(). Why not also the
other torture_hrtimeout_*() functions? The theory is that most absolute
times will be in nanoseconds, especially not (say) jiffies.
