[PATCH 2/2] x86: coding style fixes to arch/x86/kernel/setup_32.c

[Paolo Ciarrocchi]

Fix one:
ERROR: do not initialise externals to 0 or NULL

The change affects the generated binary file:

paolo@paolo-desktop:/tmp/a$ size setup_32.o*
   text    data     bss     dec     hex filename
   3526    7406     885   11817    2e29 setup_32.o
   3526    7406     885   11817    2e29 setup_32.o.after
   3526    7410     885   11821    2e2d setup_32.o.after.initialise

paolo@paolo-desktop:/tmp/a$ md5sum setup_32.o*
d238f977facb3b4e4ee6a18390678376  setup_32.o
d238f977facb3b4e4ee6a18390678376  setup_32.o.after
1c43448c2f50d22215857741ffe5eca5  setup_32.o.after.initialise
