drm/i915: Squelch any ktime/jiffie rounding errors for wait-ioctl
We wait upon jiffies, but report the time elapsed using a
high-resolution timer. This discrepancy can lead to us timing out the
wait prior to us reporting the elapsed time as complete.
This restores the squelching lost in commit e95433c73a11 ("drm/i915:
Rearrange i915_wait_request() accounting with callers").
Fixes: e95433c73a11 ("drm/i915: Rearrange i915_wait_request() accounting with callers")
