Subject: [PATCH AUTOSEL 5.7 075/274] ice: Change number of XDP TxQ to 0 when destroying rings

From: Marta Plantykow <marta.a.plantykow@...el.com>

[ Upstream commit c8f135c6ee7851ad72bd4d877216950fcbd45fb6 ]

When XDP Tx rings are destroyed the number of XDP Tx queues
is not changing. This patch is changing this number to 0.
