vfs/tar: return inode numbers of null records

Browse Source 
The tar vfs plugin returns an inode value of zero and a type directory
for null records, which wrongly triggers the file-system loop detection
of the find utility. This patch returns the node pointer as inode value
instead, which is a unique value.

Fixes #3695
