xen/arm64: Add missing synchronization barrier in invalidate_cache

The invalidation of the instructions cache requires barriers to ensure
the completion of the invalidation before continuing (see B2.3.4 in ARM
DDI 0487A.j).

This was overlooked in commit fb9d877 "xen/arm64: Add an helper to
invalidate all instruction caches".
