[PATCH 2/2] PCI: Fix double mem region release in devm_pci_remap_cfg_resource()

[Ladislav Michl]

devm_release_mem_region() is called explicitely in case
devm_pci_remap_cfgspace() fails, however the same release
function is later called also as devres release of
devm_request_mem_region() causing double resource free.

Fixes: 490cb6ddb17d ("PCI: Implement devm_pci_remap_cfgspace()")
