Richard Yao d954ca19ba Fix theoretical "use-after-free" in dbuf_prefetch_indirect_done() 
Coverity complains about a "use-after-free" bug in
`dbuf_prefetch_indirect_done()` because we use a pointer value after
freeing its buffer. The pointer is used for refcounting in ARC (as the
reference holder). There is a theoretical situation where the pointer
would be reused in a way that causes the refcounting to collide, so we
change the order in which we call arc_buf_destroy() and
dbuf_prefetch_fini() to match the rest of the function. This prevents
the theoretical situation from being a possibility.

Also, we have a few return statements with a value, despite this being a
void function. We clean those up while we are making changes here.
