Subject: [PATCH] Use out of range value when the number of files can't be
 determined

Trying to get the number of files of a torrent with no metadata causes
a crash. Prevent this by first checking if the metadata is available.
If the number of files can't be determined, -1 will be returned.

Closes #2522.
