preproc: Fix to reset %rep list line number after every iteration
preproc: Fix to reset %rep list line number after every iteration

The code has been fixed to print the corresponding line
numbers of %rep blocks correctly, but only for the first
iteration. For the subsequent iterations, the current line
number on the expansion needs to be explicitly reset again.

Fixes: ab6f8319552f ("listing: when listing lines in macros
and rep blocks, show the actual line")
