mtd: rawnand: pasemi: Fix the probe error path
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 commitd44154f969
("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. Fixes:d44154f969
