Fix display of line numbers with fonts larger than the default

* src/xdisp.c (maybe_produce_line_number): Update the metrics in
IT, not in IT->glyph_row, since the latter gets overwritten in
display_line.  Fixes display of line numbers when the font used
for them is larger than that of the default face.
