#10169: Double Fault Exception on usb boot x86_64

Comment (by korli):
It seems the kernel stack is the same size on 32-bit and 64-bit, which
might explain the behavior difference between architectures. The following
patch fixes the problem by increasing the kernel stack size by another
page.
Is it OK as is or would it be better to differentiate with B_HAIKU_64_BIT?
