[PATCH] mtd: nand: fix mention to CONFIG_MTD_NAND_ECC_BCH

[Erico Nunes]

Mention to CONFIG_MTD_ECC_BCH in the warning message can be confusing as this
doesn't match the exact name of the configuration option.
This warning showed up once to me when I was starting to set up BCH. After
checking my .config file, it took a moment before realizing it is
CONFIG_MTD_NAND_ECC_BCH instead of CONFIG_MTD_ECC_BCH.

Not sure if CONFIG options should be printed in the log at all, but
the correct option is better than an incorrect one. Seeing as
CONFIG_MTD_ECC_BCH doesn't actually exist:
