selinux: reduce the number of calls to synchronize_net() when flushing caches
When flushing the AVC, such as during a policy load, the various network caches are also flushed, with each making a call to synchronize_net() which has shown to be expensive in some cases. This patch consolidates the network cache flushes into a single AVC callback which only calls synchronize_net() once for each AVC cache flush.
