Following the CSI specification, values that are included in the
VolumeUsage MUST NOT be negative. However, CephFS seems to return -1 for
the number of inodes that are available. Instead of returning a
negative value, set it to 0 so that it will not get included in the
encoded JSON response.
Updates: #2579
