Subject: [PATCH] x86, MCE: clean up trivial coding style problem

There are a lot of white-spaces that against the rule of coding style
in __mcheck_cpu_apply_quirks(). This problem had been introduced by
'575203b4747c(x86, MCE, AMD: Disable error thresholding bank 4
on some models)' and '2e6f694fde0a(x86, mce: port K7 bank 0 quirk
to 64bit mce code)'

This may be an insignificant patch. However, if we allow them continue
to survive, then this may make someone uncomfortable.
