hwmon: chipcap2: enable IRQ processing when regulator is already enabled

Browse Source 
cc2_enable() returns early when the regulator is already enabled.
This can happen if a previous regulator_disable() failed or if the
regulator was configured as always-on.

In this case, process_irqs remains false, causing the ready interrupt
to be ignored. Subsequent operations waiting for the ready completion
then time out.

Set process_irqs before returning when the regulator is already
enabled, so that the driver continues to process ready interrupts.
