[ Upstream commit d6ff32478d7e95d6ca199b5c852710d6964d5811 ]

The pm_runtime_enable will decrement the power disable depth. Imbalance
depth will resulted in enabling runtime PM of device fails later.  Thus
a pairing decrement must be needed on the error handling path to keep it
balanced.

Runtime pm APIs")
