Subject: Do not draw anything during DrawLogo.
X-Git-Tag: edk2-stable201903~17618

Do not draw anything during DrawLogo.

Previously a series of diagonal color lines would be drawn to the
screen, and then quickly replaced by the boot logo.  Now the
screen will remain black until the boot logo is shown.
