Subject: [PATCH] iscsi-target: fix extract_param to handle buffer length
 corner case

extract_param() is called with max_length set to the total size of the
output buffer.  It's not safe to allow a parameter length equal to the
buffer size as the terminating null would be written one byte past the
end of the output buffer.
