[PATCH 08/10] mm: make vmalloc.c explicitly non-modular

[Paul Gortmaker]

The Kconfig currently controlling compilation of this code is CONFIG_MMU
which is per arch, but in all cases it is bool or def_bool meaning that
it currently is not being built as a module by anyone.

Lets remove the couple traces of modularity so that when reading the
code there is no doubt 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 subsys_initcall might make more sense here.
