PM: hibernate: fix load_image_and_restore() error path
As 'swsusp_check' open 'hib_resume_bdev', if call 'create_basic_memory_bitmaps' failed, we need to close 'hib_resume_bdev' in 'load_image_and_restore' function. Signed-off-by: Ye Bin <yebin10@huawei.com> [ rjw: Subject ] Signed-off-by: Rafael J. Wysocki <rafael.j.wysocki@intel.com>
