bpf: restore wakeup softint

This change fixes the issue that fownsignal which can take an
adaptive mutex is called inside a pserialize read section in
bpf_deliver.

Fix issue #4 (only the latter of two) in PR#58596
bpf: protect selnotify and selrecord with bd_buf_mtx

We have to make updates and checks of buffers and calls of
selnotify/selrecord atomic to satisfy constraints of sel* API.

Also, bd_state and bd_cv are protected by bd_buf_mtx now.

Fix issue #3 of PR#58596

Part of the fix is inspired by riastradh's patch.
