[Intel-wired-lan] [PATCH] i40e: Fix use of uninitialized variable

[Alex Dewar]

In i40e_clean_rx_irq_zc(), the variable failure is only set when a
condition is met, but then its value is used unconditionally. Fix this.

Addresses-Coverity: 1496986 ("Uninitialized value")
Fixes: 8cbf74149903 ("i40e, xsk: move buffer allocation out of the Rx processing loop")
