ocfs2: Set inline xattr entries with ocfs2_xa_set()
ocfs2_xattr_ibody_set() is the only remaining user of ocfs2_xattr_set_entry(). ocfs2_xattr_set_entry() actually does two things: it calls ocfs2_xa_set(), and it initializes the inline xattrs. Initializing the inline space really belongs in its own call. We lift the initialization to ocfs2_xattr_ibody_init(), called from ocfs2_xattr_ibody_set() only when necessary. Now ocfs2_xattr_ibody_set() can call ocfs2_xa_set() directly. ocfs2_xattr_set_entry() goes away. Another nice fact is that ocfs2_init_dinode_xa_loc() can trust i_xattr_inline_size.
