[PATCH] kernel: make module.c itself more explicitly non-modular

[Paul Gortmaker <paul.gortmaker@windriver.com>]

The Kconfig currently controlling compilation of this code is:

menuconfig MODULES
   bool "Enable loadable module support"

...meaning that it currently is not being built as a module by anyone.
No surprise here, since modular support being a module would be an
interesting chicken before the egg problem.

Lets remove the use of module_init in this code so that when reading
the file, there is less doubt that it is builtin-only.

Since module_init translates to device_initcall in the non-modular
case, the init ordering remains unchanged with this commit.  However
one could argue that fs_initcall makes more sense for proc stuff,
and we can change the initcall order later and watch for fallout
if so desired.

We can't of course delete the module.h include in this case since it
is used all through the rest of the file.

[I was undecided as to whether we should do this in one step
 or two, i.e. instead just make the change to fs_initcall here
 and now, and so went with the more cautious/granular approach.]
