> This patch fixes following memory leaks.
> - When open() is failed, uio_res and fds won't be freed in
>   pci_uio_map_resource().
> - When pci_map_resource() is failed but path is allocated correctly,
>   path and fds won't be freed in pci_uio_map_recource().
>   Also, some mapped resources should be freed.
> - When pci_uio_unmap() is called, path should be freed.
> 
> Also, fixes below.
> - When pci_map_resource() is failed, mapaddr will be MAP_FAILED.
>   In this case, pci_map_addr should not be incremented in
>   pci_uio_map_resource().
> - To shrink code, move close().
> - Remove fail variable.
