usb: ehci-spear: fix call balance of sehci clk handling routines
If the clock sehci->clk was not enabled in spear_ehci_hcd_drv_probe,
it should not be disabled in any path.
Conversely, if it was enabled in spear_ehci_hcd_drv_probe, it must be disabled
in all error paths to ensure proper cleanup.
Found by Linux Verification Center (linuxtesting.org) with Klever.
