Subject: [PATCH 4.4 082/149] media: omap3isp: Add missed v4l2_ctrl_handler_free() for preview_init_entities()

From: Chuhong Yuan <hslester96@...il.com>

[ Upstream commit dc7690a73017e1236202022e26a6aa133f239c8c ]

preview_init_entities() does not call v4l2_ctrl_handler_free() when
it fails.
Add the missed function to fix it.

Fixes: de1135d44f4f ("[media] omap3isp: CCDC, preview engine and resizer")
