[U-Boot] [PATCH v2] ubi: Ensure no fastmap flush after uif_close

[Martin Townsend]

On detach UBI attempts to update fastmap after closing user interfaces
but at this point UBI volumes have already been free()'ed and fastmap
can no longer access these data structures.

Changes for v2:
   - Fix by removing update to fastmap from ubi_fastmap_close instead
     of reordering uif_close and ubi_wl_close in ubi_detach_mtd_dev
