UBI: add missing kmem_cache_free() in process_pool_aeb error path
commit 1bf1890e86869032099b539bc83b098be12fc5a7 upstream.
I ran into this error after a ubiupdatevol, because I forgot to backport
e9110361a9a4 UBI: fix the volumes tree sorting criteria.
UBI error: process_pool_aeb: orphaned volume in fastmap pool
UBI error: ubi_scan_fastmap: Attach by fastmap failed, doing a full scan!
kmem_cache_destroy ubi_ainf_peb_slab: Slab cache still has objects

UBI: scanning is finished
Freeing the cache in the error path fixes the Slab error.
Tested on at91sam9g35 (3.14.18+fastmap backports)
