net/ifup.c: don't fail silently
Since commit a162dfe the ifup command is
implemented in C and runs up to two external scripts.
If one of these scripts return with an error code, the command terminates
silently. This can confuse a user because there is no hint about the reason
why it fails. Add error messages to avoid this case.
