ice: add ndo_bpf callback for safe mode netdev ops
ice driver requires a programmable pipeline firmware package in order to
have a support for advanced features. Otherwise, driver falls back to so
called 'safe mode'. For that mode, ndo_bpf callback is not exposed and
when user tries to load XDP program, the following happens:
$ sudo ./xdp1 enp179s0f1
libbpf: Kernel error message: Underlying driver does not support XDP in native mode
link set xdp fd failed
which is sort of confusing, as there is a native XDP support, but not in
the current mode. Improve the user experience by providing the specific
ndo_bpf callback dedicated for safe mode which will make use of extack
to explicitly let the user know that the DDP package is missing and
that's the reason that the XDP can't be loaded onto interface currently.
