provider/aws: Updating the aws_efs_mount_target dns_name (#11023)

Browse Source 
Fixes:#10902

AWS introduced a change to the Mount Target DNS Name to remove the
availability_zone from it -
https://aws.amazon.com/about-aws/whats-new/2016/12/simplified-mounting-of-amazon-efs-file-systems/

This was because there used to be a limit of 1 mount target per AZ -
this has been raised.
