kexec: updates for 7.4-rc1

* Fix probe error codes and error propagation:
  * make architecture functions that probe loaded image consistenly return
    -ENOEXEC when they do not recognize the image format
  * Make kexec_image_probe_default() to distinguish image format mismatches
    (-ENOEXEC) from real errors (e.g. -ENOMEM), propagating real errors
    immediately and only continuing to the next loader on -ENOEXEC
* Make sure the next kernel does not land on hardware-poisoned pages
* Remove unused arch_kexec_locate_mem_hole hook
