x86: setup stack canary for the idle threads

Browse source

The idle threads for non-boot CPUs are a bit special in how they
are created; the result is that these don't have the stack canary
set up properly in their PDA. Easiest fix is to just always set
the PDA up correctly when entering the idle thread; this is a NOP
for the boot cpu.
