libceph: use %s instead of %pE in dout()s
Commit d30291b985d1 ("libceph: variable-sized ceph_object_id") changed dout()s in what is now encode_request() and ceph_object_locator_to_pg() to use %pE, mostly to document that, although all rbd and cephfs object names are NULL-terminated strings, ceph_object_id will handle any RADOS object name, including the one containing NULs, just fine. However, it turns out that vbin_printf() can't handle anything but ints and %s - all %p suffixes are ignored. The buffer %p** points to isn't recorded, resulting in trash in the messages if the buffer had been reused by the time bstr_printf() got to it. Signed-off-by: Ilya Dryomov <idryomov@gmail.com>
