 Two fixes for the AMD MCE driver:
 
   - Populate the per CPU MCA bank descriptor pointer only after it has been
     completely set up to prevent a use-after-free in case that one of the
     subsequent initialization step fails
 
   - Implement a proper release function for the sysfs entries of MCA
     threshold controls instead of freeing the memory right in the CPU
     teardown code, which leads to another use-after-free when the
     associated sysfs file is opened and accessed.
