iio: imu: kmx61: Balance runtime pm + use pm_runtime_resume_and_get()

Browse source 
No point in calling pm_runtime_put_noidle() that isn't balancing a get.
Note no actual impact because the runtime pm core protects against
a negative reference counter.

For the pm_runtime_resume_and_get() main interest is in clearing
out this old pattern to avoid it getting coppied into new submissions.
