UBIFS: fix use of freed ubifs_orphan objects
The last orphan in the cnext list has its cnext set to NULL. Because of that, ubifs_delete_orphan assumes that it is not on the cnext list and frees it immediately instead of adding it to the dnext list. The freed orphan is later modified by write_orph_node. This can cause various inconsistencies including directory entries that cannot be removed and this error: UBIFS error (pid 20685): layout_cnodes: LPT out of space at LEB 14:129009 needing 17, done_ltab 1, done_lsave 1 This is a regression introduced by "7074e5eb UBIFS: remove invalid reference to list iterator variable". This change adds an explicit flag to ubifs_orphan indicating whether it is pending commit.
