Use the correct calculations for eol_byte_num and pkt_per_line.

Nit: this line duplicates commit subject and thus is mostly useless.

Currently, pkt_per_line is calculated by dividing slice_per_intf by
slice_count. This is incorrect, as slice_per_intf should be divided by
slice_per_pkt, which is not always equivalent to slice_count as it is
possible for there to be multiple soft slices per interface even though
a panel only specifies one slice per packet.

For eol_byte_num, the current calculation describes the size of the
trailing bytes in the line. Change the calculation so that it describes
the number of padding bytes instead.
