CVE-2022-50520

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

drm/radeon: Fix PCI device refcount leak in radeon_atrm_get_bios()

As comment of pci_get_class() says, it returns a pci_device with its
refcount increased and decreased the refcount for the input parameter
@from if it is not NULL.

If we break the loop in radeon_atrm_get_bios() with 'pdev' not NULL, we
need to call pci_dev_put() to decrease the refcount. Add the missing
pci_dev_put() to avoid refcount leak.
