Hou Tao 7d3d6fc18c ubi: fastmap: Free unused fastmap anchor peb during detach ... [ Upstream commit c16f39d14a ] When CONFIG_MTD_UBI_FASTMAP is enabled, fm_anchor will be assigned a free PEB during ubi_wl_init() or ubi_update_fastmap(). However if fastmap is not used or disabled on the MTD device, ubi_wl_entry related with the PEB will not be freed during detach. So Fix it by freeing the unused fastmap anchor during detach.
