Richard Genoud 7a6f66a916 UBI: add missing kmem_cache_free() in process_pool_aeb error path 
commit 1bf1890e86 upstream.

I ran into this error after a ubiupdatevol, because I forgot to backport
e9110361a9 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)
