libpci: Do not call unversioned symbols from libpci itself

libpci: Do not call unversioned symbols from libpci itself

Windows version of GNU LD has bugs which cause that linker would translate
this unknown unversioned symbols to some random version.

So change pci_fill_info() to pci_fill_info_v38() in lib/filter.c to ensure
that last version of this function would be used also by Windows version of
GNU LD linker.

Before this change GNU LD translated this function call to symbol
_pci_fill_info@LIBPCI_3.0. After this change GNU LD translate it to
_pci_fill_info@LIBPCI_3.8.
