[XFS] sanitize xfs_initialize_vnode
Sanitize setting up the Linux indode. Setting up the xfs_inode <-> inode link is opencoded in xfs_iget_core now because that's the only place it needs to be done, xfs_initialize_vnode is renamed to xfs_setup_inode and loses all superflous paramaters. The check for I_NEW is removed because it always is true and the di_mode check moves into xfs_iget_core because it's only needed there. xfs_set_inodeops and xfs_revalidate_inode are merged into xfs_setup_inode and the whole things is moved into xfs_iops.c where it belongs.
