[PATCH 5/5] scripts: kwbimage: fix wrong return values on some errors

[Ahmad Fatoum]

Coccinelle detected that bootfrom and nandeccmode are unsigned, but
check to be less than zero. Both are only used to hold the return value
of functions that either return up to 0xFF on success and a negative
error code otherwise. It's thus safe to make them signed. Do so.
