#1385762 — [PATCH v2] lib: make sg_pool tristate instead of bool

The recently added Kconfig controlling compilation of this code is:

lib/Kconfig:config SG_POOL
lib/Kconfig:    def_bool n

...meaning that it currently is not being built as a module by anyone,
and that tripped my audit looking for modular code that is essentially
orphaned (i.e. module_exit, and .remove fcns in non-modular drivers.)

In the following discussion, Ming Lin indicated that the original
intention was to have it tristate, so here we convert it accordingly.

Also fix up a couple spelling issues that appear in the surrounding
patch context.

[v2: drop modular code removal patch in favour of supporting a modular
 build via a one line Kconfig patch as per Ming's comments.  Build tested
 for allmodconfig on ARM and x86-64 on linux-next.   ]

The patch is useless, we should just ignore it.
