While these aren't generally visible from userland, it's best to be
consistent with timestamp handling. When adjusting the quota, update the
mtime and ctime like we would with a write operation on any other inode,
and avoid updating the atime which should only be done for reads.

Christian,
Would you mind picking this into the vfs.ctime branch, assuming the GFS2
maintainers ack it? Andreas and I had discussed this privately, and I
think it makes sense as part of that series.
Thanks,
Jeff
