pci: fix resource release when unmapping

Browse Source 
This patch fixes wrong resource release of pci_uio_unmap().
The 'path' member of mapped_pci_resource structure is allocated by
primary process, but currently it will be freed by both primary
and secondary process.
The patch fixes to be freed by only primary process.
