void pointers do not need to be cast to other pointer types.

The semantic patch used to find this:

@r@
expression x;
void* e;
type T;
identifier f;

(
  *((T *)e)

  ((T *)x)[...]

  ((T *)x)->f

The HW hasn't been sold since 2005, and the SW has definite bit rot.
Its time to remove it.  So move it to staging for a few releases and
then remove it after that.

There is a path in handle_vq() where kmem_cache_free() can be called
with pointer to a local variable.  It can happen if vq_repbuf_alloc()
failed to allocate memory from cache and req is NULL.

The patch adds check if cache memory was allocated before freeing it.

Fix a place where we might dereference a NULL pointer; this fixes
Coverity CID 1392.  On inspection I also found a place where we could
attempt to kmem_cache_free() a NULL pointer, so fix this too.
