x86/kexec: Fix double-free of elf header buffer

After

  b3e34a47f9 ("x86/kexec: fix memory leak of elf header buffer"),

freeing image->elf_headers in the error path of crash_load_segments()
is not needed because kimage_file_post_load_cleanup() will take
care of that later. And not clearing it could result in a double-free.

Drop the superfluous vfree() call at the error path of
crash_load_segments().
