ocfs2/xattr: Only set buffer update if it doesn't exist in cache.
When we call ocfs2_init_xattr_bucket, we deem that the new buffer head will be written to disk immediately, so we just use sb_getblk. But in some cases the buffer may have already been in ocfs2 uptodate cache, so we only call ocfs2_set_buffer_uptodate if the buffer head isn't in the cache.
