[arch][arm64] Add a dsb to context switch on smp system.
...
Fixes a crash where a thread would get preempted and move to another
cpu before executing the dsb in arm64_mmu_unmap. This would leave the
old mapping in the tlb, since the cpu that executed the dsb did not
have any pending tlb maintenance operations.
