xdp: fix bug in devmap teardown code path
Like cpumap teardown, the devmap teardown code also flush remaining
xdp_frames, via bq_xmit_all() in case map entry is removed. The code
can call xdp_return_frame_rx_napi, from the the wrong context, in-case
ndo_xdp_xmit() fails.
Fixes: 389ab7f01af9 ("xdp: introduce xdp_return_frame_rx_napi")
Fixes: 735fc4054b3a ("xdp: change ndo_xdp_xmit API to support bulking")
