Subject: [net-next v2 09/15] ice: Correct setting VLAN pruning

From: Brett Creeley <brett.creeley@...el.com>

VLAN pruning is not always being set correctly due to a previous change
that set Tx antispoof off. ice_vsi_is_vlan_pruning_ena() currently checks
for both Tx antispoof and Rx pruning. The expectation for this function is
to only check Rx pruning so fix the check.

Fixes: cd6d6b83316a ("ice: Fix VF spoofchk")
