s390/qeth: fix length check in SNMP processing
The response for a SNMP request can consist of multiple parts, which the cmd callback stages into a kernel buffer until all parts have been received. If the callback detects that the staging buffer provides insufficient space, it bails out with error. This processing is buggy for the first part of the response - while it initially checks for a length of 'data_len', it later copies an additional amount of 'offsetof(struct qeth_snmp_cmd, data)' bytes. Fix the calculation of 'data_len' for the first part of the response. This also nicely cleans up the memcpy code.
