m68k: Fix lost column on framebuffer debug console
commit 210a1ce8ed4391b64a888b3fb4b5611a13f5ccc7 upstream. Move the cursor position rightward after rendering the character, not before. This avoids complications that arise when the recursive console_putc call has to wrap the line and/or scroll the display. This also fixes the linewrap bug that crops off the rightmost column. When the cursor is at the bottom of the display, a linefeed will not move the cursor position further downward. Instead, the display scrolls upward. Avoid the repeated add/subtract sequence by way of a single subtraction at the initialization of console_struct_num_rows.
