ubi: fastmap: Don't produce the initial next anchor PEB when fastmap is disabled
Following process triggers a memleak caused by forgetting to release the
initial next anchor PEB (CONFIG_MTD_UBI_FASTMAP is disabled):
1. attach -> __erase_worker -> produce the initial next anchor PEB
2. detach -> ubi_fastmap_close (Do nothing, it should have released the
initial next anchor PEB)
Don't produce the initial next anchor PEB in __erase_worker() when fastmap
is disabled.
