media: vivid: use vfree() instead of kfree() for dev->bitmap_cap
syzkaller reported crashes on kfree() called from
vivid_vid_cap_s_selection(). This looks like a simple typo, as
dev->bitmap_cap is allocated with vzalloc() throughout the file.
Fixes: ef834f7836ec0 ("[media] vivid: add the video capture and output
parts")
