Subject: documentation/dev-manual/dev-manual-kernel-appendix.xml: Added note

The example that changes the kernel configuration by enabling multiple
processor support failed.  The reason is because of bug 2256.
This bug was discovered during Release 1.2.  Apparently it also
affects 1.1.2.  I have added the Note explaining the bug.

(From yocto-docs rev: 6a0af8103b24a0b24ffd0e29873feeb685e1cf5e)
