SCTP: assure size before attempting checksum calculation
When checksum calculations are performed (irrespective of type) the
calculation is assumed to be possible on at least a common header and
optionally a payload. This assumption was not checked, which could
lead to out of bound access of packet buffer data.
Simply adding the assurance that enough buffer data is available avoids
this out of bound access.
