Eric Dumazet f607a15800 garp: remove last synchronize_rcu() call
When removing last vlan from a device, garp_uninit_applicant() calls
synchronize_rcu() to make sure no user can still manipulate struct
garp_applicant before we free it.

Use call_rcu() instead, as a step to further net_device dismantle
optimizations.

Add the temporary garp_cleanup_module() function to make sure no pending
call_rcu() are left at module unload time [ this will be removed when
kfree_rcu() is available ]
