xfs: log timestamp changes to the source inode in rename

Now that we don't mark VFS inodes dirty anymore for internal
timestamp changes, but rely on the transaction subsystem to push
them out, we need to explicitly log the source inode in rename after
updating it's timestamps to make sure the changes actually get
forced out by sync/fsync or an AIL push.

We already account for the fourth inode in the log reservation, as a
rename of directories needs to update the nlink field, so just
adding the xfs_trans_log_inode call is enough.

This fixes the xfsqa 065 regression introduced by:

	"xfs: don't use vfs writeback for pure metadata modifications"
