usb: dwc3: st: fix probed platform device ref count on probe error path

In the Linux kernel, the following vulnerability has been resolved:

usb: dwc3: st: fix probed platform device ref count on probe error path

The probe function never performs any paltform device allocation, thus
error path "undo_platform_dev_alloc" is entirely bogus.  It drops the
reference count from the platform device being probed.  If error path is
triggered, this will lead to unbalanced device reference counts and
premature release of device resources, thus possible use-after-free when
releasing remaining devm-managed resources.

CWE-416 Use After Free

The product reuses or references memory after it has been freed. At some point afterward, the memory may be allocated again and saved in another pointer, while the original pointer references a location somewhere within the new allocation. Any operations using the original pointer are no longer valid because the memory "belongs" to the code that operates on the new pointer.
