Input: wm97xx-core - only schedule interrupt handler if not already scheduled
As well as clarifying the fact that the driver can cope if a second
interrupt occurs before the IRQ work is scheduled this also ensures
that calls to the machine irq_enable() are balanced, making that easier
to implement. Normally this is redundant due to the interrupt disabling
but some unusal board configurations can trigger it.
