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.
