UBI: add missing kmem_cache_free() in process_pool_aeb error path
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!

Tested on at91sam9g35 (3.14.18+fastmap backports)
