fix data loss issue if using existing azure disk with partitions in disk mount
**What this PR does / why we need it**:
When use an existing azure disk(also called [static provisioning](https://github.com/andyzhangx/demo/tree/master/linux/azuredisk#static-provisioning-for-azure-disk)) in pod, if that disk has multiple partitions, the disk will be formatted in the pod mounting.
This PR removes `formatIfNotFormatted` func in `WaitForAttach` which uses `lsblk` command to check whether disk is formatted or not
b87a392b1a/pkg/volume/azure_dd/azure_common_linux.go (L213-L215)
And finally the format disk operation will happen in `MountDevice` in which it uses common k8s code(`SafeFormatAndMount.GetDiskFormat`) using `blkid` to detect disk format, `blkid` could detect multiple partitions
b87a392b1a/pkg/util/mount/mount_linux.go (L541-L543)
- so if we use common k8s code(`SafeFormatAndMount.GetDiskFormat`), following error will be returned for mulitple partition disks, which is expected:
