kexec: prevent double free on image allocation failure
If kimage_normal_alloc() fails to initialize an allocated kimage, it will free the image but would still set 'rimage', as a result kexec_load will try to free it again. This would explode as part of the freeing process is accessing internal members which point to uninitialized memory. Signed-off-by: Sasha Levin <sasha.levin@oracle.com> Cc: "Eric W.
