msm: camera: cdm: check irq status on hang detection

Check IRQ status on hang detection; if the inline IRQ
is set then the cdm has triggered IRQ but there is a
workqueue scheduling delay which is causing the cdm
config timeout. To prevent the timeout due to
scheduling check the work record and irq status.
