xfs: remove deprecated sysctls 

xfsbufd_centisecs and age_buffer_centisecs were due for removal in
3.14. We forgot to do that - it's now well past time to remove these
deprecated, unused sysctls.

Deprecated Sysctls
==================
fs.xfs.xfsbufd_centisecs (Min: 50 Default: 100 Max: 3000)
Dirty metadata is now tracked by the log subsystem and
flushing is driven by log space and idling demands. The
xfsbufd no longer exists, so this syctl does nothing.
None at present.
