powerpc: introduce die_mce
As explained by commit daf00ae71dad ("powerpc/traps: restore
recoverability of machine_check interrupts"), die() can't be called from
within nmi_enter to nicely kill a process context that was interrupted.
nmi_exit must be called first.
This adds a function die_mce which takes care of this for machine check
handlers.
