mtd: nand: brcmnand: Zero bitflip is not an error

Browse source

A negative return value of brcmstb_nand_verify_erased_page() indicates a
real bitflip error of an erased page, and other return values (>= 0) show
the corrected bitflip number. Zero return value means no bitflip, but the
current driver code treats it as an error, and eventually leads to
falsely reported ECC error.
