commit fc62113b32c95906b3ea8ba42e91014c7d0c6fa6 upstream.

When the SD host controller tries to probe again due to the derferred
probe mechanism, it will always keep the SD host device as runtime
resume state due to missing the runtime put operation in error path
last time.

Thus add the pm_runtime_put_noidle() in error path to make the PM runtime
counter balance, which can make the SD host device's PM runtime work well.
