media: v4l2-ctrls-api.c: add back dropped ctrl->is_new = 1

Browse source 
The patch adding support for dynamically allocated arrays accidentally
dropped the line setting ctrl->is_new to 1, thus new string values were
always ignored.

Fixes: fb582cba44 ("media: v4l2-ctrls: add support for dynamically allocated arrays.")
