* fhandler_disk_file.cc (path_conv::ndisk_links): Rename from num_entries.

Accept an argument and calculate any extra links needed based on missing .  and
..  entries.
(fhandler_disk_file::fstat_helper): Always call pc->ndisks_links() to calculate
the number of links.
* path.h (path_conv::ndisk_links): Declare.
