tun: replace get_cpu_ptr with this_cpu_ptr when bh disabled
tun_xdp_one() runs with local bh disabled. So there is no need to disable preemption by calling get_cpu_ptr while updating stats. This patch replaces the use of get_cpu_ptr() with this_cpu_ptr() as a micro-optimization. Also removes related put_cpu_ptr call. Acked-by:Jason Wang <jasowang@redhat.com> Signed-off-by:
