KVM: arm64: Use debug_owner to track if debug regs need save/restore
Use the debug owner to determine if the debug regs are in use instead of
keeping around the DEBUG_DIRTY flag. Debug registers are now
saved/restored after the first trap, regardless of whether it was a read
or a write. This also shifts the point at which KVM becomes lazy to
vcpu_put() rather than the next exception taken from the guest.
