IB/cxgb4: Fix if statement in pick_local_ip6adddrs

This fixes an if statement checking the return value of the function
get_lladdr for success in the function pick_local_ip6addrs to instead
of directly checking the return value of this call check the opposite
as get_lladdr returns zero for success which would incorrectly make
this if statement block not execute with the current if statement
check.
