vt(9): couple of small issues

I used to have mousechar_start="3" in my r.conf. To be honest I can not even
recall why. But this worked fine with syscons without any glitches.
With vt I get the following during boot up:
vidcontrol: setting mouse character: Inappropriate ioctl for device
And mouse cursor is never drawn, apparently vidcontrol -m on -M <X> just fails.
Looks like with syscons MOUSE_MOUSECHAR ioctl is handled by a terminal device
and consolectl device while with vt it is handled only by sysmouse device.
Another issue is that I see the following messages appearing during boot and
from time to time afterwards in the system log:
kernel: sysmouse: unknown ioctl: t:40007413
kernel: sysmouse: unknown ioctl: t:80007410
The ioctls seem to be TIOCFLUSH and TIOCGETA, so I am not sure why sysmouse gets
involved. Maybe the same issue exists with syscons's sysmouse as well, but it
is just silent about it.
Seems like ioctls are called by X server. For example:
