Currently, the logic to return an ath12k_sta pointer, given a ieee80211_sta pointer, uses typecasting throughout the driver. In general, conversion functions are preferable to typecasting since using a conversion function allows the compiler to validate the types of both the input and output parameters. ath12k already defines a conversion function ath12k_vif_to_arvif() for a similar conversion. So introduce ath12k_sta_to_arsta() for this use case, and convert all of the existing typecasting to use this function.
