Dan Carpenter 5d3805af27 ubi: Fix an error pointer dereference in error handling code 
If "seen_pebs = init_seen(ubi);" fails then "seen_pebs" is an error pointer
and we try to kfree() it which results in an Oops.

This patch re-arranges the error handling so now it only frees things
which have been allocated successfully.

Fixes: daef3dd1f0 ("UBI: Fastmap: Add self check to detect absent PEBs")
