arm64: hibernate: check pgd table allocation
There is a bug in create_safe_exec_page(), when page table is allocated
it is not checked that table is allocated successfully:
But it is dereferenced in: pgd_none(READ_ONCE(*pgdp)). Check that
allocation was successful.
Fixes: 82869ac57b5d ("arm64: kernel: Add support for hibernate/suspend-to-disk")
