[PATCH net 0/6] gve: various XDP fixes

[Joshua Washington <joshwash@google.com>]

This patch series includes a number of XDP-related fixes, both in the
control plane and the dataplane.

A summary of the changes:
1) fix an issue where XDP packets weren't being counted against NAPI
   budget
2) fix an issue where XSK buffers that have not been processed are
   leaked when disabling XSK pools
3) fix an XSK buffer leak when an RX error descriptor comes back from
   the hardware
4) fix a NULL dereference due to incorrect registration of XSK pools on
   queues not set up in XSK zero copy mode
5) fix a deadlock introduced by attempting to acquire the netdev lock
   after it has already been acquired
6) fix a racy NULL dereference due to DMA umapping the XSK pool before
   queues are fully stopped
