According to ipmi spec, block number is a number that is incremented,
starting with 0, for each new block of message data returned using the
Middle transaction.
Here, the 'blocknum' is data[0] which always starts from zero(0) and
'ssif_info->multi_pos' starts from 1.
So, we need to add +1 to blocknum while comparing with multi_pos.
This change fixes ("ipmi:ssif: Fix handling of multi-part return
messages").
