usb: ehci-hcd: fix call balance of clocks handling routines
If the clocks priv->iclk and priv->fclk were not enabled in ehci_hcd_sh_probe,
they should not be disabled in any path.
Conversely, if they was enabled in ehci_hcd_sh_probe, they must be disabled
in all error paths to ensure proper cleanup.
Found by Linux Verification Center (linuxtesting.org) with Klever.
