net/mlx4_core: Protect port type setting by mutex
We need to protect set_port_type() for concurrency, as the sysfs code could
call it from mutliple contexts in parallel.
The port_mutex is not enough because we need to protect from concurrent
modification of 'info' and stopping of the port sensing work.
