powerpc/kdump: Fix timeout in crash_kexec_wait_realmode
commit 63f21a56f1cc0b800a4c00349c59448f82473d19 upstream.
The existing code it pretty ugly. How about we clean it up even more
like this?
From: Anton Blanchard <anton@samba.org>
We check for timeout expiry in the outer loop, but we also need to
check it in the inner loop or we can lock up forever waiting for a
CPU to hit real mode.
