s390/qeth: pass TSO header length to fill_buffer()
The TSO code already calculates the length of its header element,
no need to duplicate this in the low-level code again.
Use this opportunity to make hd_len unsigned, and for TSO match
its calculation to what tso_fill_header() does.
No functional change.
