Daniel Borkmann f267f26281 xdp, bonding: Fix feature flags when there are no slave devs anymore ... Commit 9b0ed890ac ("bonding: do not report NETDEV_XDP_ACT_XSK_ZEROCOPY") changed the driver from reporting everything as supported before a device was bonded into having the driver report that no XDP feature is supported until a real device is bonded as it seems to be more truthful given eventually real underlying devices decide what XDP features are supported. The change however did not take into account when all slave devices get removed from the bond device. In this case after 9b0ed890ac, the driver keeps reporting a feature mask of 0x77, that is, NETDEV_XDP_ACT_MASK & ~NETDEV_XDP_ACT_XSK_ZEROCOPY whereas it should have reported a feature mask of 0. Fix it by resetting XDP feature flags in the same way as if no XDP program is attached to the bond device. This was uncovered by the XDP bond selftest which let BPF CI fail. After adjusting the starting masks on the latter to 0 instead of NETDEV_XDP_ACT_MASK the test passes again together with this fix.
