Subject: [PATCH] PCI: j721e: Fix an error handling path in 'j721e_pcie_probe()'

If an error occurs after a successful 'cdns_pcie_init_phy()' call, it must
be undone by a 'cdns_pcie_disable_phy()' call, as already done above and
below.

Update the 'goto' to branch at the correct place of the error handling
path.

Fixes: 49e0efdce791 ("PCI: j721e: Add support to provide refclk to PCIe connector")
