    mtd: nand: omap: fix compile warning on ‘erased_sector_bitflips’
    
    Commit 2c9f2365 (mtd: nand: omap: ecc.calculate: merge omap3_calculate_ecc_bch4
    in omap_calculate_ecc_bch) introduced minor compile warning
    "‘erased_sector_bitflips’ defined but not used [-Wunused-function]" when
    compiling without CONFIG_MTD_NAND_OMAP_BCH. Move function
    erased_sector_bitflips() into the same ifdef section as the only caller.
