In dev_map_bpf_prog_run(), xdp.txq and xdp.rxq are assigned the same
stack-local pointers on every iteration. xdp_convert_frame_to_buff()
does not modify these fields, so the assignments are loop-invariant.

Hoist them before the loop, matching the pattern already used by
cpu_map_bpf_prog_run_xdp() in cpumap.c.

No functional change.
