[PATCH v4 1/2] iio: gyro: mpu3050-i2c: fix pm_runtime error handling

[Antoniu Miclaus]

The return value of pm_runtime_get_sync() is not checked, and the
function always returns success. This allows I2C mux operations to
proceed even when the device fails to resume.

Use pm_runtime_resume_and_get() and propagate its return value to
properly handle resume failures.
