s390/qeth: tidy up parameter naming for qeth_do_send_packet()

Cppcheck reports the following for drivers/s390/net/qeth_core.h:

    warning - line 1560 - Function 'qeth_do_send_packet' argument order
    different:
    declaration 'card, queue, skb, hdr, hd_len, offset, elements'
    definition  'card, queue, skb, hdr, offset, hd_len, elements_needed'.

Match the naming in the function's declaration against its definition.
