[PATCH] ext2: Enable atomic inode security labeling

This patch modifies ext2 to call the inode_init_security LSM hook to obtain
the security attribute for a newly created inode and to set the resulting
attribute on the new inode.  This parallels the existing processing for
setting ACLs on newly created inodes.
