[PATCH] net: ehea: unwind probe_port sysfs file on failure

[Pengpeng Hou]

ehea_create_device_sysfs() creates probe_port and then remove_port. If
the second device_create_file() fails, the helper returns the error but
leaves probe_port installed even though probe treats the sysfs setup as
failed.

Remove probe_port on the remove_port creation failure path so the helper
leaves no partial sysfs state behind.
