John Strunk 55881f2fc4 Improve efficiency of csiMountMgr.GetAttributes ...

GetAttributes is called repeatedly while setting the fsGroup of a
volume. Previously, it recalculated whether SELinux was supported during
each call. This resulted in volume.SetVolumeOwnership taking a long
time, delaying pod startup for high file count volumes.

This change checks the SELinux status once, right after node publish,
allowing GetAttributes to simply build and return a struct.
