x86/boot/compressed: Don't declare __force_order in kaslr_64.c
GCC 10 changed the default to -fno-common, which leads to

    LD      arch/x86/boot/compressed/vmlinux
  ld: arch/x86/boot/compressed/pgtable_64.o:(.bss+0x0): multiple definition of `__force_order'; \
    arch/x86/boot/compressed/kaslr_64.o:(.bss+0x0): first defined here
  make[2]: *** [arch/x86/boot/compressed/Makefile:119: arch/x86/boot/compressed/vmlinux] Error 1

Since __force_order is already provided in pgtable_64.c, there is no
need to declare __force_order in kaslr_64.c.
