iwlwifi: mvm: synchronize firmware DMA paging memory
When driver needs to access the contents of a streaming DMA buffer without unmapping it it should call dma_sync_single_for_cpu(). Once the call has been made, the CPU "owns" the DMA buffer and can work with it as needed. Before the device accesses the buffer, however, ownership should be transferred back to it with dma_sync_single_for_device(). Both calls weren't performed by the driver, resulting with odd paging errors on some platforms. Fix it.
