[PATCH 15/20] fs: ceph: Initialize filesystem timestamp ranges

[Deepa Dinamani <deepa.kernel@gmail.com>]

Fill in the appropriate limits to avoid inconsistencies
in the vfs cached inode times when timestamps are
outside the permitted range.

According to the disscussion in
https://patchwork.kernel.org/patch/8308691/ we agreed to use
unsigned 32 bit timestamps on ceph.
Update the limits accordingly.
