Tao Chen 5d9bc98187 bpf: Remove preempt_disable in bpf_try_get_buffers ...

[ Upstream commit 4223bf833c ]

Now BPF program will run with migration disabled, so it is safe
to access this_cpu_inc_return(bpf_bprintf_nest_level).

Fixes: d9c9e4db18 ("bpf: Factorize bpf_trace_printk and bpf_seq_printf")
