af_unix: Remove unix_table_locks.
unix_table_locks are to protect the global hash table, unix_socket_table.
The previous commit removed it, so let's clean up the unnecessary locks.
Here is a test result on EC2 c5.9xlarge where 10 processes run concurrently
in different netns and bind 100,000 sockets for each.
without this series : 1m 38s
with this series : 11s
It is ~10x faster because the global hash table is split into 10 netns in
this case.
