qcacld-3.0: Introduce hdd roam profile accessor functions

Currently the roam profile associated with an adapter, along with two
accessory buffers, are located within the adapter's hdd_wext_state
structure. However the roam profile is independent of wireless
extensions (WEXT) support, so there is a plan to relocate these
structures. In order to facilitate this relocation first introduce
accessor functions.
