PM / hibernate: Check the success of generating md5 digest before hibernation

Browse source

Currently if get_e820_md5() fails, then it will hibernate nevertheless.
Actually the error code should be propagated to upper caller so that
the hibernation could be aware of the result and terminates the process
if md5 digest fails.
