ASoC: wcd_cpe_core: Perform irq cleanup once the bus is up

During subsystem restart, it is possible that while the underlying bus
is down, the irq driver has already performed its cleanup. In such case,
when CPE driver requests to cleanup its own irq, the irq driver attempts
to hold an lock that is already freed. Fix this issue by performing the
CPE driver irq cleanup after bus is up rather than when bus is down.
