msm: camera: cdm: Fix CDM IRQ handling

Issue:
In CDM irq handling, workq to handle the irq was
scheduled before clearing the status registers. Due
to which reset complete can be done before clearing
the status registers. This creates a possibility of
issuing next reset before clearing the status registers.

Fix:
Clear the status registers before scheduiling workq to
handle interrupt. Also moved the reset done logic from
workq to interrupt handler for quick handling of reset
irq.
