x86: fix runtime error in arch/x86/kernel/cpu/mcheck/mce_amd_64.c

Browse source 
This problem is due to the kobject rework recently done in this file.

The mce_amd_64.c code uses some wierd forward calls to back out of the
recursive way the code creates kobjects.  Because of this, we need to
verify that we have really created a kobject before calling
kobject_uevent().

Many thanks to Yinghai Lu <yhlu.kernel@gmail.com> for reporting the
problem and testing.
