description:
Reset flip/flop using dedicated vga_reset_state() macro we already have.
Explicit vga_raw_read() used here before was incorrect since it reads
from *wrong* io handle!

Fixes weird problem under VirtualBox where first switch to a different
VT caused text mode color 0 (normally black) to become something else.
