drivers: video: shell: fix control name lookup

video_shell_get_ctrl_by_name() normalized the search string (`name`)
instead of the control's actual name (`cq->name`). This made the
comparison always succeed on the first control, causing incorrect
lookups at runtime.

Update the code to normalize `cq->name` before comparison so that
each control name is correctly checked against the search string.
