sparc: use scnprintf() in show_pciobppath_attr() in pci.c
snprintf() returns the number of bytes that would be written,
which may be greater than the the actual length to be written.
show_pciobppath_attr() should return the number of bytes printed
into the buffer. This is the return value of scnprintf().
