MCE: Don't run 32bit machine checks with interrupts on

Browse Source 
Running machine checks with interrupt on is a extremly bad idea. The machine
check handler only runs when the system is broken and needs to finish
as quickly as possible.

Remove the respective bogus post 2.6.27 regression and call
the machine check vector directly again.

This removes only code.
