mtd: parsers: afs: Fix freeing the part name memory in failure
In the case of failure while parsing the partitions, the iterator should be pre decremented by one before starting to free the memory allocated by kstrdup(). Because in the failure case, kstrdup() will not succeed and thus no memory will be allocated for the current iteration.
