Because that's not the first #include in every file.

The #define pr_fmt has to be before anything that
includes kernel.h so it's safest/best to have it
be the first thing in the file.

At some point in the next year or so, all of the
uses of:

#define pr_fmt(fmt) KBUILD_MODNAME ": " fmt

should be removed and that should become the default.
