iio: light: gp2ap002: Fix unbalanced runtime PM on repeated event writes

In the Linux kernel, the following vulnerability has been resolved:

iio: light: gp2ap002: Fix unbalanced runtime PM on repeated event writes

The IIO core does not filter duplicate writes to the event enable
attribute, so writing the same value twice invokes
write_event_config() twice. Enabling twice leaks a runtime PM
reference, preventing the device from ever suspending again;
disabling twice underflows the usage count and triggers a
"Runtime PM usage count underflow" warning.

Bail out early when the requested state matches the current state.
While at it, switch to pm_runtime_resume_and_get() so a failed
resume is propagated to userspace instead of silently marking the
event enabled.
