[PATCH] nvme: initialize identify ns data to NULL

[Tokunori Ikegami]

Currently nvme_identify_ns() sets the data to NULL if failed.
Also the data is not freed if the function returned failure.
But correctly the data should be initialized to NULL.
So to make sure fix to initialize the data to NULL.
