Subject: selinux: fix uninitalised stack variable read in sel_netport_init

After the removal of the avc_add_callback() in commit 615e51fdda6
("selinux: reduce the number of calls to synchronize_net() when flushing caches"),
ret is never set to anything, but we return uninitialized stack data on success.

Given the absense of other failure paths, just explicitly return 0.
