[Intel-wired-lan] [next PATCH S27 13/15] i40e/i40evf: use logical operators, not bitwise

[Joshua Hay]

From: Mitch Williams <mitch.a.williams at intel.com>

Mr. Spock would certainly raise an eyebrow to see us using bitwise
operaters, when we should clearly be relying on logic. Fascinating.

Testing Hints: No functional change, but the code is more correct.
Make sure it compiles and passes traffic properly.
