There is asymmetry between ath12k_core_init and() ath12k_core_deinit(). 
It will cause page fault in some case. Reorder and relocate the release of
resources in ath12k_core_deinit() to avoid this asymmetry issue.

  wifi: ath12k: Reorder and relocate the release of resources in
    ath12k_core_deinit()
  wifi: ath12k: Adjust the process of resource release for ahb bus
