bonding: do not report NETDEV_XDP_ACT_XSK_ZEROCOPY
Do not report the XDP capability NETDEV_XDP_ACT_XSK_ZEROCOPY as the
bonding driver does not support XDP and AF_XDP in zero-copy mode even
if the real NIC drivers do.
Note that the driver used to report everything as supported before a
device was bonded. Instead of just masking out the zero-copy support
from this, have the driver report that no XDP feature is supported
until a real device is bonded. This seems to be more truthful as it is
the real drivers that decide what XDP features are supported.
Fixes: cb9e6e584d58 ("bonding: add xdp_features support")
