Title:
  Volume status set to "error extending" when driver fails to extend the
  volume

Status in Cinder:
  Invalid
Status in OpenStack Dashboard (Horizon):
  Invalid

Bug description:
  If the driver can't extend the volume because there's no enough space,
  the volume status is set to "error_extending" and the volume becomes
  unusable. The only options to the users are to delete the volume and
  create it again.

  Expected behavior would be: if the back-end doesn't have enough
  capacity to extend the volume, warn user with proper information and
  set volume status back to 'available' since the volume is untouched.
