Dan Carpenter 6ad7f52d8c ceph: fix type promotion bug on 32bit systems ...

commit 07bb00ef00 upstream.

In this code "ret" is type long and "src_objlen" is unsigned int.  The
problem is that on 32bit systems, when we do the comparison signed longs
are type promoted to unsigned int.  So negative error codes from
do_splice_direct() are treated as success instead of failure.
