[PATCH 5.12 194/292] watchdog: keembay: Removed timeout update in the TO ISR

[ Upstream commit 3168be5d66ac6c3508a880022f79b5a887865d5d ]

In the TO ISR removed updating the Timeout value because
its not serving any purpose as the timer would have already expired
and the system would be rebooting.
