Albert Hsieh 6de1b002a2 mtd: nand: brcmnand: Zero bitflip is not an error 
[ Upstream commit e44b9a9c13 ]

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.

Fixes: 02b88eea9f ("mtd: brcmnand: Add check for erased page bitflip")
