iio: light: gp2ap002: re-enable irq if runtime suspend fails
gp2ap002_runtime_suspend() disables the irq before writing OPMOD. If
the write fails, the callback returns an error with the irq still
disabled while the PM core marks the device active again.
re-enable the irq before returning the error so the irq state matches
the active state the PM core restores.
