[PATCH] PCI: v3-semi: Fix a memory leak in some error handling paths in 'v3_pci_probe()'

[Christophe JAILLET]

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.

Fixes could be older than this commit, but this is as far as git can go.

There is also a 'clk_prepare_enable()' which looks un-ballanced. I don't
know if it can be an issue.

Compile tested only.
