[PATCH] media: stm32: dcmipp: Propagate runtime resume errors

[Pengpeng Hou]

dcmipp_runtime_resume() can fail while preparing the device clocks, but
dcmipp_resume() currently ignores the result of
pm_runtime_force_resume() and always returns success.

Return the pm_runtime_force_resume() result so system resume does not
hide a failed runtime resume.
