powerpc/kasan: Disable address sanitization in kexec paths

The kexec code paths involve code that necessarily run in real mode, as
CPUs are disabled and control is transferred to the new kernel. Disable
address sanitization for the kexec code and the functions called in real
mode on CPUs being disabled.

 Daniel's and wrote the commit message.]
