ceph: preserve I_COMPLETE across rename
d_move puts the renamed dentry at the end of d_subdirs, screwing with our
cached dentry directory offsets. We were just clearing I_COMPLETE to avoid
any possibility of trouble. However, assigning the renamed dentry an
offset at the end of the directory (to match it's new d_subdirs position)
is sufficient to maintain correct behavior and hold onto I_COMPLETE.
This is especially important for workloads like rsync, which renames files
into place. Before, we would lose I_COMPLETE and do MDS lookups for each
file. With this patch we only talk to the MDS on create and rename.
