ceph: fix a buffer leak in __ceph_setxattr()

Browse source

commit 5d3cc36b4e upstream.

The old_blob in __ceph_setxattr() can store
ci->i_xattrs.prealloc_blob value during the retry.
However, it is never called the ceph_buffer_put()
for the old_blob object. This patch fixes the issue of
the buffer leak.
