usb: ehci-omap: Fix PM disable depth umbalance in ehci_hcd_omap_probe 



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.
