x86/mce: Stop mce_reign() from re-computing severity for every CPU
Back in commit: 20d51a426fe9 ("x86/mce: Reuse one of the u16 padding fields in 'struct mce'") a field was added to "struct mce" to save the computed error severity. Make use of this in mce_reign() to avoid re-computing the severity for every CPU. In the case where the machine panics, one call to mce_severity() is still needed in order to provide the correct message giving the reason for the panic.
