mlx4_core: change log_num_{qp,rdmarc} with scale_profile

When module parameter 'scale_profile' is set we
use different (than default) parameter values for
certain mlx4_core module parameters which define
some resource limits.

This changes 'log_num_qp' and 'log_num_rdmarc'
to lower values to fix some issues leading to
undesirable HCA resource usage. These led to
undesirable behavior in conjunction with current
round-robin allocation of QPs where some
long-lasting QPs "polluted" ICM memory chunks.
