afs: afs_write_end() should change i_size under the right lock
[ Upstream commit 1f32ef79 ] Fix afs_write_end() to change i_size under vnode->cb_lock rather than ->wb_lock so that it doesn't race with afs_vnode_commit_status() and afs_getattr(). The ->wb_lock is only meant to guard access to ->wb_keys which isn't accessed by that piece of code.
