Update mounter interface in volume manager

Browse Source 
Update mounter interface in volume manager's ActualStateOfWorld every time.
Otherwise kubelet uses the first mounter it gets, which may not have the
latest information.

This fixes set up of CSI volumes, which store information about SELinux
support in their `mounter` interface implementation. With each MountVolume()
retry, a new mounter is instantiated and only the final mounter that succeeds
has the right info if the volume supports SELinux or not and can later
return the right attributes on GetAttributes() call.
