Merge branch 'xsk: another round of fixes'

====================

Hello,

yet another fixes for XSK from Magnus and me.

Magnus addresses the fact that xp_alloc() can return NULL, so this needs
to be handled to avoid clearing entries in the SW ring on driver side.
Then he addresses the off-by-one problem in Tx desc cleaning routine for
ice ZC driver.

From my side, I am adding protection to ZC Rx processing loop so that
cleaning of descriptors wouldn't go over already processed entries.
Then I also fix an issue with assigning XSK pool to Tx queues.

This is directed to bpf tree.

Thanks!
