s390/qeth: pass full data length to l2_fill_header()
For IQD we already need to fix up the qeth_hdr's length field, and
future changes will require more flexibility for OSA as well. The
device-specific path knows best what header length it requires, so just
pass it from there.
While at it, remove the unused qeth_card parameter.
No functional change.
