x86/mce: Fix 32-bit build

Got bitten again by the BIT() macro:

 arch/x86/kernel/cpu/mcheck/mce.c: In function '__mcheck_cpu_apply_quirks':
 arch/x86/kernel/cpu/mcheck/mce.c:1453:6: warning: left shift
 count >= width of type arch/x86/kernel/cpu/mcheck/mce.c:1454:7: warning: left shift count >= width of type

Fix it already.
