When net devices propagate xdp configurations to slave devices, or when
core propagates xdp configuration to a device, we will need to perform
a memory provider check to ensure we're not binding xdp to a device
using unreadable netmem.

Currently ->ndo_bpf calls are all over the place. Adding checks to all
these places would not be ideal.

Refactor all the ->ndo_bpf calls into one place where we can add this
check in the future.

Sorry the patch title should just be:

[PATCH net-next v1] net: refactor ->ndo_bpf calls into dev_xdp_propagate

v1, not v21.
