We continue refactoring ath12k in preparation for supporting Multi-Link
Operation. For example, in this patchset we modify station state handling and
start to use more link level configuration.

Please review.

v2:

* patch 1: maintain sta state in ahsta (offline change from Aditya)

   sta state is not per link level hence there is no point in keeping it in
   arsta level. Hence move it to ahsta instead. Even mac80211 keeps sta state
   on per MLD sta level instead of link sta.

* patch 1: minor code refactoring and removing redundant codes (offline change from Aditya)

   For ML station remove, redundant code was written in different function.
   However, existing flow code can be leveraged to perform same operations.

* patch 1: ath12k_mac_assign_link_sta(): remove unnecessary synchronize_rcu()

* patch 1: ath12k_mac_free_unassign_link_sta(): remove unnecessary forward declaration

* patch 1: fold ath12k_mac_unassign_link_sta() into ath12k_mac_free_unassign_link_sta()

* patch 2: ath12k_mac_alloc_assign_link_sta(): use kmalloc()
