x86/mce/severity: Fix warning about indented braces

Dan reported compiler warnings about missing curly braces in
mce_severity_amd(). Reindent the catch-all "return MCE_AR_SEVERITY"
correctly to single tab.

While at it, chain ctx == IN_KERNEL check with mcgstatus check to make
it cleaner, as suggested by Boris.

No functional changes are introduced by this patch.
