[PATCH 5.10 316/717] phy: renesas: rcar-gen3-usb2: disable runtime pm in case of failure

[Greg Kroah-Hartman]

From: Wang Li <wangli74@xxxxxxxxxx>

[ Upstream commit 51e339deab1e51443f6ac3b1bd5cd6cc8e8fe1d9 ]

pm_runtime_enable() will decrease power disable depth. Thus a pairing
increment is needed on the error handling path to keep it balanced.
