net/mlx5: Reduce command polling interval
Use cond_resched() instead of usleep_range() to decrease the time
between polling attempts thus reducing overall driver load time.
Below is a comparison before and after the change, of loading eight
virtual functions.
Before:
real 0m8.785s
user 0m0.093s
sys 0m0.090s
After:
real 0m5.730s
user 0m0.097s
sys 0m0.087s
