Ard Biesheuvel d849da88f7 x86/efistub: Revert to heap allocated boot_params for PE entrypoint ...

commit ae835a96d7 upstream.

This is a partial revert of commit

  8117961d98 ("x86/efi: Disregard setup header of loaded image")

which triggers boot issues on older Dell laptops. As it turns out,
switching back to a heap allocation for the struct boot_params
constructed by the EFI stub works around this, even though it is unclear
why.
