dma-buf: remove redundant initialization of sg_table
sg_table is being initialized and is never read before it is updated again later on, hence making the initialization redundant. Remove the initialization. Detected by clang scan-build: "warning: Value stored to 'sg_table' during its initialization is never read" Signed-off-by: Colin Ian King <colin.king@canonical.com> Reviewed-by: Chris Wilson <chris@chris-wilson.co.uk> Signed-off-by: Daniel Vetter <daniel.vetter@ffwll.ch> Link: https://patchwork.freedesktop.org/patch/msgid/20170914230516.6056-1-colin.king@canonical.com
