staging: gasket: cleanup extended page table map/unmap

Make sure to use dma_sync_single_for_device whenever updating the
contents of an extended page table. This performs the cache flush using
the correct function from the DMA-API. Also move this call outside of
the inner loop to improve performance.

Tested: Ran run_tests with inception, testfullyconnected with parameter
caching, and rnntransducerdecoderpie107m on AT Enterprise.
