Looks like book3s/32 doesn't set RI on machine check, so
checking RI before calling die() will always be fatal
allthought this is not an issue in most cases.
Fixes: b96672dd840f ("powerpc: Machine check interrupt is a non-maskable
interrupt")
Fixes: daf00ae71dad ("powerpc/traps: restore recoverability of machine_check
interrupts")
