[S390] xpram: Remove checksum validation for suspend/resume
Currently in the suspend process checksums for the XPRAM partitions are created and stored. During the resume process it is checked, if the checksums are still the same. If this is not the case, a kernel panic is triggered. Unfortunately this prevents XPRAM from beeing used as suspend device, because in this case after the checksum has been created, the memory image is written to XPRAM and therefore the contents of the suspend partition is changed. In order to allow XPRAM to be used as suspend device, this patch removes the checksum validation.
