ext4: properly align shifted xattrs when expanding inodes

commit 443a8c41cd49de66a3fda45b32b9860ea0292b84 upstream.

We did not count with the padding of xattr value when computing desired
shift of xattrs in the inode when expanding i_extra_isize. As a result
we could create unaligned start of inline xattrs. Account for alignment
properly.
