mtd: rawnand: pasemi: Fix the probe error path

Browse source 
commit f51466901c07e6930435d30b02a21f0841174f61 upstream.

nand_cleanup() is supposed to be called on error after a successful
call to nand_scan() to free all NAND resources.

There is no real Fixes tag applying here as the use of nand_release()
in this driver predates by far the introduction of nand_cleanup() in
commit d44154f969 ("mtd: nand: Provide nand_cleanup() function to free NAND related resources")
which makes this change possible, hence pointing it as the commit to
fix for backporting purposes, even if this commit is not introducing
any bug.
