[PATCH] mtd: rawnand: ndfc: use devm_kasprintf for mtd name

[Rosen Penev <rosenp@gmail.com>]

Convert the mtd->name allocation from kasprintf() plus a manual kfree()
in the error path and in ndfc_remove() to the managed
devm_kasprintf() helper. The name is now released automatically with
the device, removing the need for explicit cleanup.
