PM / Hibernate: Return error code when alloc_image_page() fails
commit 2e725a065b0153f0c449318da1923a120477633d upstream.
Currently we return 0 in swsusp_alloc() when alloc_image_page() fails.
Fix that. Also remove unneeded "error" variable since the only
useful value of error is -ENOMEM.
[rjw: Fixed up the changelog and changed subject.]
