Arvind Sankar 9d1b5a8c72 efi/x86: Free efi_pgd with free_pages() ... [ Upstream commit c2fe61d8be491ff8188edaf22e838f819999146b ] Commit d9e9a64180 ("x86/mm/pti: Allocate a separate user PGD") changed the PGD allocation to allocate PGD_ALLOCATION_ORDER pages, so in the error path it should be freed using free_pages() rather than free_page(). Commit 06ace26f4e ("x86/efi: Free efi_pgd with free_pages()") fixed one instance of this, but missed another. Move the freeing out-of-line to avoid code duplication and fix this bug.
