powerpc/pseries: Fix kexec on recent firmware versions
Recent versions of firmware will fail to unmap the virtual processor
area if we have a dispatch trace log registered. This causes kexec
to fail.
If a trace log is registered this patch unregisters it before the
SLB shadow and virtual processor areas, fixing the problem.
The address argument is ignored by firmware on unregister so we
may as well remove it.
