archive_read_disk_posix: Don't pass -1 to a function expecting errno

This fixes an unhelpful "Couldn't visit directory: Unknown error: -1" message.

Fixes:		3311bb52cbe4 ("Bring the code supporting directory traversals from bsdtar/tree.[ch] into archive_read_disk.c and modify it. Introduce new APIs archive_read_disk_open and archive_read_disk_descend.")
