        - fixed error message coding style
        - fixed comment in ldlm_internal

This is the patch that breaks the build, again, always test it before
sending it out.

Here is just one error from the build with this patch enabled, there
were lots and lots of others:

In file included from ./drivers/staging/lustre/lustre/include/lustre_net.h:63:0,
                 from ./drivers/staging/lustre/lustre/include/obd_class.h:37,

I've applied the first 2 patches in this series, so please fix and rebase and
resend the rest.
