efi/x86: Free efi_pgd with free_pages()
Commit
d9e9a6418065 ("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
06ace26f4e6f ("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.
