We are checking for (EXT3_SB(inode->i_sb)->s_inode_size <=
EXT3_GOOD_OLD_INODE_SIZE) to find out if we can set in-inode attributes;
the test fails for inodes that have been created before the ea-in-inode
patch. Those inodes have (i_extra_isize == 0), so we end up with the
attributes overlapping the i_extra_isize field. Checking for
(i_extra_isize == 0) instead fixes this case.
The EXT3_STATE_XATTR flag is only set if (i_extra_isize > 0) and the
inodes has in-inode attributes, so that is enough in the first two
tests.
