mtd: nand: onfi don't WARN if we are in 16 bits mode
Commit ff3206b2450499203532af2505a7f6f8413e92c0 ('mtd: nand: onfi need
to be probed in 8 bits mode') adds a WARN if the onfi probe is in 16
bits mode. This allows to detect driver that need to be fixed, but this
is a bit noisy¹. Transform the WARN in a pr_err.
