[NTOSKRNL]

- Disable displaying string by bootvid after successful kernel phase 1 initialization, so there won't be graphical glitches at the top of screen if system has screen debugging enabled
- Make screen black right after phase 1 initialization finish instead of waiting 5 seconds. It removes black rectangle which appeared for me in explorer.
- Initialize some global variables in inbv.c (it was done by compiler before)
