Subject: [PATCH] media: exynos4-is: remove redundant check on type

From: Colin Ian King <colin.king@...onical.com>

The check to see if type is V4L2_BUF_TYPE_VIDEO_CAPTURE_MPLANE is redundant
as this has been already checked at the start of the function and if
it's not that value then -ENOSYS is returned. Hence the sprintf can be
replaced by a simpler string copy.

Detected by CoverityScan, CID#1309450 ("Logically dead code")
