Fixed a memory leak in stripe translator.

When iobuf is created it has reference count = 1.
After iobref_add (local->iobref, iobuf); reference count becomes 2.
After iobref_unref(local->iobref); it becomes 1 and never becomes 0.
So iobuf never deletes and this causes a memory leak.

I emulated it, creating files on brick manually.
After 5 mins of:
while true; do dd if=file of=/dev/zero bs=16384; done
top showed me this:
4618 root      20   0 1721m 1.5g 1868 S  0.0 16.2   5:41.77 glusterfs

1.5 gb of memory has leaked.

For what this if for? Can it be true in the normal conditions?
if ((local->replies[i].op_ret < local->replies[i].requested_size) &&
    (local->stbuf_size > (local->offset + op_ret))) {
May be delete it entirely?
