PM / Hibernate: user.c, fix SNAPSHOT_SET_SWAP_AREA handling

Browse source 
When CONFIG_DEBUG_BLOCK_EXT_DEVT is set we decode the device
improperly by old_decode_dev and it results in an error while
hibernating with s2disk.

All users already pass the new device number, so switch to
new_decode_dev().
