PCI: endpoint: Destroy the EPC device in devm_pci_epc_destroy()

Browse Source 
[ Upstream commit d4929755e4 ]

The devm_pci_epc_destroy() comment says destroys the EPC device, but it
does not actually do that since devres_destroy() does not call
devm_pci_epc_release(), and it also can not fully undo what the API
devm_pci_epc_create() does, so it is faulty.

Fortunately, the faulty API has not been used by current kernel tree.  Use
devres_release() instead of devres_destroy() so the EPC device will be
released.
