Jiale Yao dd30c10ff6 iio: accel: kxcjk-1013: reject duplicate event disable 
The IIO core does not filter duplicate writes to the event enable
attribute. kxcjk1013_write_event_config() already ignores repeated
enable requests, but a repeated disable request still calls
kxcjk1013_set_power_state(data, false), dropping a runtime PM reference
that was not acquired for this request. This can underflow the runtime
PM usage count and trigger a "Runtime PM usage count underflow" warning.

Return early when the requested state already matches ev_enable_state.

Fixes: b4b491c083 ("iio: accel: kxcjk-1013: Support thresholds")
