[PATCH AUTOSEL 4.19 457/671] ceph: fix "ceph.dir.rctime" vxattr value

From: David Disseldorp <ddiss@suse.de>

[ Upstream commit 718807289d4130be1fe13f24f018733116958070 ]

The vxattr value incorrectly places a "09" prefix to the nanoseconds
field, instead of providing it as a zero-pad width specifier after '%'.
