media: uvcvideo: Fix double free in error path
commit c6ef3a7fa97ec823a1e1af9085cf13db9f7b3bac upstream.
If the uvc_status_init() function fails to allocate the int_urb, it will
free the dev->status pointer but doesn't reset the pointer to NULL. This
results in the kfree() call in uvc_status_cleanup() trying to
double-free the memory. Fix it by resetting the dev->status pointer to
NULL after freeing it.
