[PATCH v2 05/16] powerpc/64s/exception: machine check pseries should always run the early handler

[Nicholas Piggin]

Now that pseries with fwnmi registered runs the early machine check
handler, there is no good reason to special case the non-fwnmi case
and skip the early handler. Reducing the code and number of paths is
a top priority for asm code, it's better to handle this in C where
possible (and the pseries early handler is a no-op if fwnmi is not
registered).
