    performance/io-cache: check for non-null gfid before calling inode_path
    
    A new non-linked inode is added to lru list. Hence it might be possible
    that gfid might be NULL when inode_dump is called. To pass asserts in
    inode_path, we've to check for non-null gfid before invoking that
    procedure.
