In case ID is not found in manufacturer table, the raw ID is printed using %*phN format which is not supported by lib/vsprintf.c. The information displayed doesn't reflect the raw ID return by the unknown spi-nand.

Use %02x format instead, as done in spi-nor-core.c.

For example, before this patch: ERROR: spi-nand: spi_nand flash@0: unknown raw ID f74ec040 after ERROR: spi-nand: spi_nand flash@0: unknown raw ID 00 c2 26 03

Fixes: 0a6d6bae0386 ("mtd: nand: Add core infrastructure to support SPI NANDs")
