watchdog: Add comments to explain the watchdog_disabled variable
The watchdog_disabled flag is a bit cryptic. However it's
usefulness is multifold. Uses are:
1. Check if smpboot_register_percpu_thread function passed.
2. Makes sure that user enables and disables the watchdog in
sequence i.e. enable watchdog->disable watchdog->enable watchdog
Unlike enable watchdog->enable watchdog which is wrong.
