Wen Yang 5d53bfdce0 mtd: phram: fix a double free issue in error path
commit 49c64df880 upstream.

The variable 'name' is released multiple times in the error path,
which may cause double free issues.
This problem is avoided by adding a goto label to release the memory
uniformly. And this change also makes the code a bit more cleaner.
