wifi: ath12k: add rx_info to capture required field from rx descriptor

Browse source

In ath12k_dp_rx_h_mpdu(), as part of undecap to native wifi mode, the rx
descriptor memory is getting overwritten. After this function call, all
the rx descriptor related memory accesses give invalid values. To handle
this scenario, introduce a new structure ath12k_dp_rx_info which
pre-caches all the required fields from the rx descriptor before calling
ath12k_dp_rx_h_ppdu(). This rx_info structure will be used in the next
patch.
