Fixes gcc '-Wunused-but-set-variable' warning:

drivers/misc/mic/scif/scif_dma.c: In function 'scif_rma_list_dma_copy_wrapper':
drivers/misc/mic/scif/scif_dma.c:1558:27: warning:
 variable 'dst_dma_addr' set but not used [-Wunused-but-set-variable]

drivers/misc/mic/scif/scif_dma.c:1558:13: warning:
 variable 'src_dma_addr' set but not used [-Wunused-but-set-variable]

They never used since introduction in
