drm/msm: avoid using 'timespec'



The timespec structure and associated interfaces are deprecated and will
be removed in the future because of the y2038 overflow.

The use of ktime_to_timespec() in timeout_to_jiffies() does not
suffer from that overflow, but is easy to avoid by just converting
the ktime_t into jiffies directly.
