video: cfb_console: fix definition and usage of CURSOR_xxx macros
The CURSOR_ON, CURSOR_OFF, and CURSOR_SET macros are defined incorrectly. If
cursor support is disabled, then these macros are defined to nothing, but
then they are used like this:
if (console_col < CONSOLE_COLS)
CURSOR_OFF
console_row++;
which was compiled like this:
if (console_col < CONSOLE_COLS)
console_row++;
This is obviously not what was intended.
