[RFC PATCH v2 08/13] sysrq: Disable bootsplash on SAK

When the user requests a clean TTY via the SAK SysRq, that means he
really wants to use the console.

Let's disable the bootsplash, even if the request is not on a VT, as
the user probably knows what he's doing and it's more helpful to get
out of his way.
