Subject: [PATCHv6 17/28] PCI: mobiveil: Remove an unnecessary return value check

The memory of private structure has been allocated together with the
pci_host_bridge structure in function devm_pci_alloc_host_bridge().
So it is unnecessary to check the return value when get the private
structure pointer.
