Mandeep Singh Baines 824c6b7f62 watchdog: Fix rounding bug in get_sample_period() ...

In get_sample_period(), softlockup_thresh is integer divided by
5 before the multiplication by NSEC_PER_SEC. This results in
softlockup_thresh being rounded down to the nearest integer
multiple of 5.

For example, a softlockup_thresh of 4 rounds down to 0.
