description:
Define the MULTIPROCESSOR cpu_number() for modules too.

Modules should work whether the main kernel is multiprocessor or not.
In particular, dtrace should not think cpu_number() is 0 while
cpu_index(curcpu()) and curcpu()->ci_index are nonzero, leading to
rather spectacularly bogus results...
