msm: limiter: Increase constraints prior changing limits

* In very rare instance, resume function causes wdog to reset
  on MSM board and hence a reboot.
* So let resume function execute and restore limits only if
  required.
* Increase suspend defer time to 10 seconds.
  (which is same as that of MSM Hotplug)
