Some arc_release() cleanup
- Don't drop L2ARC header if we have more buffers in this header.
Since we leave them the header, leave them the L2ARC header also.
Honestly we are not required to drop it even if there are no other
buffers, but then we'd need to allocate it a separate header, which
we might drop soon if the old block is really deleted.  Multiple
buffers in a header likely mean active snapshots or dedup, so we
know that the block in L2ARC will remain valid.  It might be rare,
but why not?
 - Remove some impossible assertions and conditions.
