[PATCH][next][V2] media: uvcvideo: remove duplicated dma_dev assignments

[Colin King]

From: Colin Ian King <colin.king@xxxxxxxxxxxxx>

The assignment to dma_dev has been performed twice in one
statement. Fix this by removing the extraneous assignment.

Addresses-Coverity: ("Evaluation order violation")
Fixes: fdcd02a641e2 ("media: uvcvideo: Use dma_alloc_noncontiguos API")
Signed-off-by: Colin Ian King <colin.king@xxxxxxxxxxxxx>

V2:  Fix 2nd occurrence of this same issue.
