e1000: fix bugs from recent commits

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.

Commit 2326a94d caused a ton of "unused variable 'x'" warnings.
Fix these.  While we are at it, remove some bogus parens.
