Subject: [PATCH] [media] coda: remove redundant call to v4l2_m2m_get_vq

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

The call to v4ls_m2m_get_vq is only used to get the return value
which is not being used, so it appears to be redundant and can
be removed.

Detected with CoverityScan, CID#1420674 ("Useless call")
