xfs: Remove deprecated xfs_bufd sysctl parameters

Commit 64af7a6 ("xfs: remove deprecated sysctls") removed the
deprecated xfsbufd-related sysctl interface, but forgot to delete the
corresponding parameters: "xfs_buf_timer" and "xfs_buf_age".

This patch removes those parameters and makes no other changes.
