unix: correctly track in-flight fds in sending process user_struct

The commit referenced in the Fixes tag incorrectly accounted the
number of in-flight fds over a unix domain socket to the original
opener of the file-descriptor. This allows another process to
arbitrary deplete the original file-openers resource limit for the
maximum of open files.

Use CVE-2016-2550.
