UBI: fix use-after-free on error path
commit e57e0d8e818512047fe379157c3f77f1b9fabffb upstream.
When we fail to erase a PEB, we free the corresponding erase entry object,
but then re-schedule this object if the error code was something like -EAGAIN.
Obviously, it is a bug to use the object after we have freed it.
