overlayfs: Fix setting IOP_XATTR flag
ovl_fill_super calls ovl_new_inode to create a root inode for the new
superblock before initializing sb->s_xattr. This wrongly causes
IOP_XATTR to be cleared in i_opflags of the new inode, causing SELinux
to log the following message:
SELinux: (dev overlay, type overlay) has no xattr support
Fix this by initializing sb->s_xattr and similar fields before calling
ovl_new_inode.
