video: driver: Fix unbalanced irq warning in interrupt handling

In case of watchdog interrupt, power off sequence will
get called which will make intr_status to 0 due to which
enable_irq gets called from isr_handler irrespective of
watchdog interrupt. Now during power up sequence again
when the enable_irq gets called, it will through
"Unbalanced enable for irq" error.
Added a fix for the same.
