Subject: [PATCH 2/3] block: make blk-throttle.c explicitly non-modular

The Kconfig currently controlling compilation of this code is:

config BLK_DEV_THROTTLING
  bool "Block layer bio throttling support"

...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.
