msm: camera: reqmgr: Pause the timer before sensor stream on

Bläddra i källkod 
Sometimes, the cpu load is very high, then the devcies
stream on will be delayed, but the CRM watchdog is already
enabled before streaming on, then we will have a chance to
notify SOF freeze issue.
This change pauses the CRM watchdog timer before streaming
on sensor and after stopping ife, when we can detect the
stream on and stream off delay, but don't notify error,
also can detect the real SOF freeze issue.
