net/mlx5e: Disable preemption when doing TC statistics upcall
When called by HW offloading drivers, the TC action (e.g
net/sched/act_mirred.c) code uses this_cpu logic, e.g
_bstats_cpu_update(this_cpu_ptr(a->cpu_bstats), bytes, packets)
per the kernel documention, preemption should be disabled, add that.
Before the fix, when running with CONFIG_PREEMPT set, we get a
BUG: using smp_processor_id() in preemptible [00000000] code: tc/3793
asserion from the TC action (mirred) stats_update callback.
Fixes: aad7e08d39bd ('net/mlx5e: Hardware offloaded flower filter statistics support')
