x86-64: Move the error_alignment label forward

Move the error_alignment label forward to avoid clang warning on

if (!bfd_set_section_alignment (ebfd, sec, 2))
  goto error_alignment;

htab = elf_x86_64_hash_table (info);

error_alignment:
  info->callbacks->einfo (_("%F%A: failed to align section\n"), sec);
                             "%F" causes a fatal linker error and
			     immediate exit.

sec = htab->elf.sgotplt;

Also fix alignment on program property note section.

	* elf64-x86-64.c (elf_x86_64_link_setup_gnu_properties): Move
	the error_alignment label forward.  Properly align program
	property note section.
