[PATCH] iavf: Remove useless else if

[Jiapeng Chong]

The assignment of the else and else if branches is the same, so the else
if here is redundant, so we remove it and add a comment to make the code
here readable.

./drivers/net/ethernet/intel/iavf/iavf_main.c:2211:6-8: WARNING: possible condition with no effect (if == else).
