mlx4_core: Increase command timeout for INIT_HCA to 10 seconds

The current INIT_HCA firmware command timeout is sufficient for the
default number of resources (QPs, CQs, etc) being allocated, but if
the HCA profile is modified to increase the amount of resources, then
a spurious timeout is detected and HCA initialization fails.

Increase the timeout for the INIT_HCA command to 10 seconds, which
also brings it into line with all the other command timeouts.
