arm64: hibernate: add __force attribute to gfp_t casting
Two new warnings are reported by sparse:
"sparse warnings: (new ones prefixed by >>)"
>> arch/arm64/kernel/hibernate.c:181:39: sparse: sparse: cast to
restricted gfp_t
>> arch/arm64/kernel/hibernate.c:202:44: sparse: sparse: cast from
restricted gfp_t
gfp_t has __bitwise type attribute and requires __force added to casting
in order to avoid these warnings.
Fixes: 50f53fb72181 ("arm64: trans_pgd: make trans_pgd_map_page generic")
