Smack: ignore private inode for smack_file_receivesubmit/tizen/20150512.061658accepted/tizen/wearable/20150513.005517accepted/tizen/tv/20150513.005305accepted/tizen/mobile/20150513.005633accepted/tizen/common/20150512.125138
The dmabuf fd can be shared between processes via unix domain
socket. The file of dmabuf fd is came from anon_inode. The inode
has no set and get xattr operations, so it can not be shared
between processes with smack. This patch fixes just to ignore
private inode including anon_inode for smack_file_receive.
