nvdimm: Split label init out from the logic for getting config data
This patch splits the initialization of the label data into two functions. One for doing the init, and another for reading the actual configuration data. The idea behind this is that by doing this we create a symmetry between the getting and setting of config data in that we have a function for both. In addition it will make it easier for us to identify the bits that are related to init versus the pieces that are a wrapper for reading data from the ACPI interface. So for example by splitting things out like this it becomes much more obvious that we were performing checks that weren't necessarily related to the set/get operations such as relying on ndd->data being present when the set and get ops should not care about a locally cached copy of the label area.
