[PATCH -next] lkdtm/bugs: make huge and ignored static

[ruanjinjie]

The symbol is not used outside of the file, so mark it static.

Fixes the following warnings:

./drivers/misc/lkdtm/bugs.c:276:23: warning: symbol 'huge'
was not declared. Should it be static?

./drivers/misc/lkdtm/bugs.c:277:23: warning: symbol 'ignored'
was not declared. Should it be static?
