From: Amir Vadai <amirv@mellanox.com>

commit 78fb2de711ec28997bf38bcf3e48e108e907be77 upstream.

filters_lock might have been used while it was re-initialized.
Moved filters_lock and filters_list initialization to init_netdev instead of
alloc_resources which is called every time the device is configured.
