leon, grspw_pkt: fixed device/dma closing
The user is now responsible to stop and close the DMA channels
before closing the device. To prevent complicated situations and
blocking the caller of grspw_close and grspw_dma_close a return
code was added to indicate to the user that the DMA may not have
been stopped or that blocked tasks are still active within the
driver for the specified device.
