tipc: add __read_mostly annotations to several global variables
Added to the following:
- tipc_random
- tipc_own_addr
- tipc_max_ports
- tipc_net_id
- tipc_remote_management
- handler_enabled
The above global variables are read often, but written rarely. Use
__read_mostly to prevent them being on the same cacheline as another
variable which is written to often, which would cause cacheline
bouncing.
