gpio: pcf857x: Check for irq_set_irq_wake() failures
If an interrupt controller doesn't support wake-up configuration,
irq_set_irq_wake() returns an error code. Then any subsequent call
trying to deconfigure wake-up will cause an imbalance, and a warning
will be printed:
WARNING: CPU: 1 PID: 1341 at kernel/irq/manage.c:540 irq_set_irq_wake+0x
Unbalanced IRQ 26 wake disable
To fix this, refrain from any further parent interrupt controller
(de)configuration if irq_set_irq_wake() failed.
