msm_11ad: update affinity to start from the first golden core 



Currently the first fastest core is chosen for affinity, in some
cases there are three clusters and the last cluster (the fastest)
include only one core.
In this case we need to choose the first core in the second
cluster to be able to support a case of multiple interrupt lines.
