PM / Hibernate: Snapshot cleanup
Remove support of reads with offset. This means snapshot_read/write_next
now does not accept count parameter. It allows to clean up the functions
and snapshot handle which no longer needs to care about offsets.
/dev/snapshot handler is converted to simple_{read_from,write_to}_buffer
which take care of offsets.
