Fix pm_runtime error handling across the mpu3050 driver. The existing
code uses pm_runtime_get_sync() without checking return values, allowing
operations to proceed even when the device fails to resume.

Replace pm_runtime_get_sync() with pm_runtime_resume_and_get() and
propagate errors appropriately. Unlike pm_runtime_get_sync(), the usage
count is not incremented on error.

Changes in v4:
- Reword commit messages to correctly attribute the unchecked return
  value to the caller rather than pm_runtime_get_sync() itself
- Simplify preenable by collapsing the trailing return statements

Applied to the fixes-togreg branch of iio.git and marked for
stable.  Thanks
