mtd: spi-nor: Reset nor->addr_width when SFDP parsing failed

Commit 5390a8df769e ("mtd: spi-nor: add support to non-uniform SFDP SPI
NOR flash memories") removed the 'nor->addr_width = 0;' statement when
spi_nor_parse_sfdp() returns an error, thus leaving ->addr_width in an
undefined state which can cause trouble when spi_nor_scan() checks its
value.
