pinctrl: qcom: Use return value from irq_set_wake() call
msmgpio irqchip was not using return value of irq_set_irq_wake() callback
since previously GIC-v3 irqchip neither had IRQCHIP_SKIP_SET_WAKE flag nor
it implemented .irq_set_wake callback. This lead to irq_set_irq_wake()
return error -ENXIO.
However from 'commit 4110b5cbb014 ("irqchip/gic-v3: Allow interrupt to be
configured as wake-up sources")' GIC irqchip has IRQCHIP_SKIP_SET_WAKE
flag.
Use return value from irq_set_irq_wake() and irq_chip_set_wake_parent()
instead of always returning success.
Fixes: e35a6ae0eb3a ("pinctrl/msm: Setup GPIO chip in hierarchy")
