Daniel Borkmann 858d68f102 bpf: bpf_event_entry_gen's alloc needs to be in atomic context

Should have been obvious, only called from bpf() syscall via map_update_elem()
that calls bpf_fd_array_map_update_elem() under RCU read lock and thus this
must also be in GFP_ATOMIC, of course.

Fixes: 3b1efb196e ("bpf, maps: flush own entries on perf map release")
