bpf: cpumap: add missing XDP_ABORTED handling in xdp prog runner

cpu_map_bpf_prog_run_xdp() handles XDP_PASS, XDP_REDIRECT, and
XDP_DROP but is missing an XDP_ABORTED case. Without it, XDP_ABORTED
falls into the default case which logs a misleading "invalid XDP
action" warning instead of tracing the abort via trace_xdp_exception().

Add the missing XDP_ABORTED case with trace_xdp_exception(), matching
the handling already present in the skb path (cpu_map_bpf_prog_run_skb),
devmap (dev_map_bpf_prog_run), and the generic XDP path (do_xdp_generic).

Also pass xdpf->dev_rx instead of NULL to bpf_warn_invalid_xdp_action()
in the default case, so the warning includes the actual device name.
This aligns with the generic XDP path in net/core/dev.c which already
passes the real device.
