EDAC, i7core: Remove double buffering of error records
In the bad old days the functions from x86_mce_decoder_chain could be called in machine check context. So we used to carefully copy them and defer processing until later. But in f29a7aff4bd60 ("x86/mce: Avoid potential deadlock due to printk() in MCE context") we switched the logging code to save the record in a genpool, and call the functions that registered to be notified later from a work queue. So drop all the double buffering and do all the work we want to do as soon as i7core_mce_check_error() is called.
