qcacmn: Extend kernel version condition in i_qdf_time.h

For kernel v3.17 and above, timekeeping.h is included for
some kernel APIs such as ktime_get() but for versions prior to 3.17,
the above APIs are present in hrtimer.h.

To accommodate the usage of these APIs for older kernel versions,
include <linux/hrtimer.h> into this file for kernel versions
lower than 3.17
