Subject: [PATCH net-next v2 4/4] e1000e: Minor flow correction in e1000_shutdown function

From: Vitaly Lifshits <vitaly.lifshits@...el.com>

Add curly braces to avoid entering to an if statement where it is not
always required in e1000_shutdown function.
This improves code readability and might prevent non-deterministic
behaviour in the future.
