e1000e: cleanup boolean logic
Replace occurrences of 'if (<bool expr> == <1|0>)' with
'if ([!]<bool expr>)'
Replace occurrences of '<bool var> = (<non-bool expr>) ? true : false'
with '<bool var> = <non-bool expr>'.
Replace occurrence of '<bool var> = <non-bool expr>' with
'<bool var> = !!<non-bool expr>'
While the latter replacement is not really necessary, it is done here for
consistency and clarity. No functional changes.
