util: if FilesystemNodeGetVolumeStats succeeds the volume is healthy

When FilesystemNodeGetVolumeStats() succeeds, the volume must be
healthy. This can be included in the VolumeCondition CSI message by
default.

Checks that detect an abnormal VolumeCondition should prevent calling
FilesystemNodeGetVolumeStats() as it is possible that the function will
hang.
