qcacld-3.0: Clean up the usage of sta_to_adapter in HDD

The mapping of sta_id to the adapter in hdd context stores the adapter
with respect to the corresponding sta_id. Currently, the mapping is not
used anywhere in the driver even though the adapters are stored in it.

As there is no usage for the mapping, remove it as a part of sta_id
cleanup effort.
