Pull UBI/UBIFS/JFFS2 updates from Richard Weinberger:
 "This pull request contains mostly fixes for UBI, UBIFS and JFFS2:

  UBI:

   - Fix a regression around producing a anchor PEB for fastmap.

     Due to a change in our locking fastmap was unable to produce fresh
     anchors an re-used the existing one a way to often.

  UBIFS:

   - Fixes for endianness. A few places blindly assumed little endian.

   - Fix for a memory leak in the orphan code.

   - Fix for a possible crash during a commit.

   - Revert a wrong bugfix.

  JFFS2:

   - Revert a bad bugfix (false positive from a code checking tool)"
