HID: Intel-thc-hid: Intel-thc: fix dma_unmap_sg() nents value

Browse source

[ Upstream commit 0e13150c1a ]

The `dma_unmap_sg()` functions should be called with the same nents as the
`dma_map_sg()`, not the value the map function returned.

Save the number of entries in struct thc_dma_configuration.
