PCI: v3-semi: Fix a memory leak in v3_pci_probe() error handling paths

[ Upstream commit bca7189 ]

If we fails somewhere in 'v3_pci_probe()', we need to free 'host'.

Use the managed version of 'pci_alloc_host_bridge()' to do that easily.
The use of managed resources is already widely used in this driver.
