[U-Boot] [PATCH] mtd: spi: don't return -1 when scan succeed

[Fabien Parent]

In spi_flash_scan, 'ret' is initialled to -1, but 'ret' is not always
used to store a return value, in that case, even when the function
succeed, an error (-1) will be returned.
Lets just return 0 if we hit the end of the function.
