[PATCH v2 3/5] ipc: fix mp channel closure to prevent message loss

[Artemy Kovalyov <artemyko@nvidia.com>]

This commit addresses an issue related to the cleanup of the
multiprocess channel. Previously, when closing the channel, there was a
risk of losing trailing messages. This issue was particularly noticeable
when broadcast message from primary to secondary processes was sent
while a secondary process was closing it's mp channel. In this fix, we
delete mp socket file before stopping mp receive thread.
