mlx4_core: Allow choosing flow steering mode
Device managed flow steering will be enabled only under administrator
directive provided through setting the existing module parameter
log_num_mgm_entry_size to -1 (if the device actually supports flow
steering). If flow steering isn't requested or not available, the
driver will use the value of log_num_mgm_entry_size and B0 steering.
