video: cfb_console: fix definition and usage of CURSOR_xxx macros

Browse source 
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.
