ext2: Fix BUG_ON in evict() on inode deletion
Commit 8e3dffc6 introduced a regression where deleting inode with large extended attributes leads to triggering BUG_ON(inode->i_state != (I_FREEING | I_CLEAR)) in fs/inode.c:evict(). That happens because freeing of xattr block dirtied the inode and it happened after clear_inode() has been called. Fix the issue by moving removal of xattr block into ext2_evict_inode() before clear_inode() call close to a place where data blocks are truncated. That is also more logical place and removes surprising requirement that ext2_free_blocks() mustn't dirty the inode.
