[U-Boot] [PATCH] env_nand: Use nand_read_skip_bad instead of nand_read

[Steve Sakoman]

The nand-read function returns an error code if correctable errors have occurred.
This is not desirable, since the errors have been corrected!

This patch switches to the nand_read_skip_bad function which does not
return an error code if the errors are correctable.
