Kernel: Fix crash when switching to console 5 & 6
The changes in commit 20743e8 removed the s_max_virtual_consoles
constant and hardcoded the number of consoles to 4. But in
PS2KeyboardDevice the keyboard shortcuts for switching to consoles were
hardcoded to 6.

I reintroduced the constant and added it in both places.
