selinux: reduce the number of calls to synchronize_net() when flushing caches

commit 615e51fdda6f274e94b1e905fcaf6111e0d9aa20 upstream.

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.
