[U-Boot] [PATCH] e1000: fix bugs from recent commits

[Marek Vasut]

> Commit 114d7fc0 "e1000: Rewrite EEPROM checksum error to give more
> information" failed to initialize the checksum variable which should
> result in random results. Fix that.
> [I wonder if that code has _ever_ been tested!!]
> 
> Commit 2326a94d caused a ton of "unused variable 'x'" warnings.
> Fix these.  While we are at it, remove some bogus parens.

> With the "checksum" variable being random (due to not being
> initialized) you should have seen serious checksum problems.
> How did this escape your testing?
> 
> And all these build warnings - have you ever actully compiled that
> code?  What's going on here???  - wd

> Marek: Could you please be so kind and have a look at the debug code?
> I think this needs a major cleanup, too.  Thanks in advance.  - wd
