[PATCH 05/16] net/i40e: remove duplicate code

[Stephen Hemminger <stephen@networkplumber.org>]

There are two branches in the cascading if/else that have same
condition and code; remove one. Update the code to follow DPDK
style where all statements in if should have brackets if any
leg requires them.
