[PATCH 12/12] mtd: nand: free allocated memory

["Brian Norris" <computersforpeace@gmail.com>]

This fixes a problem from:

  commit f2f4772692cf3f31eb73d46337c7f10bd031bc26
  mtd: nand: remove NAND_BBT_SCANBYTE1AND6 option

In reverting pieces of another commit, I accidentally removed a line
that shold have stayed. We should free up the memory we allocated upon
releasing our device.

This should probably just be squashed in with the buggy commit (it
hasn't been brought upstream yet...)
