Subject: ptp: ocp: Fix error path for pci_ocp_device_init()
Patch-mainline: v5.15-rc1
Git-commit: d9fdbf132dab4d844167004ae4ca979fbebd9871
References: jsc#SLE-19253

If ptp_ocp_device_init() fails, pci_disable_device() is skipped.
Fix the error handling so this case is covered.  Update ptp_ocp_remove()
so the normal exit path is identical.
