kernel: media: uvcvideo: Remove dangling pointers

A dangling pointer vulnerability was found in the Linux kernel. When an async control is written, a copy of a pointer is made in the file handle that started the operation. If the user closes that file descriptor, its structure will be freed and there will be one dangling pointer per pending asyn...
