x86, NMI: Remove DIE_NMI_IPI
With priorities in place and no one really understanding the difference between
DIE_NMI and DIE_NMI_IPI, just remove DIE_NMI_IPI and convert everyone to DIE_NMI.
This also simplifies default_do_nmi() a little bit. Instead of calling the
die_notifier in both the if and else part, just pull it out and call it before
the if-statement. This has the side benefit of avoiding a call to the ioport
to see if there is an external NMI sitting around until after the (more frequent)
internal NMIs are dealt with.
