[PATCH v3 2/2] pci: endpoint: Fix kernel panic after put_device()

[Rolf Evers-Fischer]

From: Rolf Evers-Fischer <rolf.evers.fischer@xxxxxxxxx>

'put_device()' calls the relase function 'pci_epf_dev_release()',
which already frees 'epf->name' and 'epf'.

Therefore we must not free them again after 'put_device()'.

Fixes: 5e8cb4033807 ("PCI: endpoint: Add EP core layer to enable EP controller and EP functions")
