net: refactor ->ndo_bpf calls into dev_xdp_propagate
When net devices propagate xdp configurations to slave devices,
we will need to perform a memory provider check to ensure we're
not binding xdp to a device using unreadable netmem.
Currently the ->ndo_bpf calls in a few places. 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.
