Fix up issue during decryption

Browse Source 
* Since some devices are unable to decrypt after processing of the fstab,
   because of the partition details updation, and after intro of dynamic partitioning
   here decryption process was going on after complete processing of the dynamic volumes.

 * This patch fix these issue, it process the logical volumes at their time not after all processing fstabs.
   This fixes the decryption issue.
   Translate more partitions i.e., ODM, Product.
   Added more partitions in unmount partitions.
