[PATCH 6/8] fs: make direct-io.c explicitly non-modular

[Paul Gortmaker]

The Makefile currently controlling compilation of this code has:

ifeq ($(CONFIG_BLOCK),y)
obj-y +=        buffer.o block_dev.o direct-io.o mpage.o

and in addition to that the Kconfig is:

block/Kconfig:menuconfig BLOCK
block/Kconfig:       bool "Enable the block layer" if EXPERT

...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 gets bumped to one level earlier when we
use the more appropriate fs_initcall here.  However we've made similar
changes before without any fallout and none is expected here either.
