compat_ioctl: handle SIOCOUTQNSD

BugLink: https://bugs.launchpad.net/bugs/1861934
commit 9d7bf41fafa5b5ddd4c13eb39446b0045f0a8167 upstream.

Unlike the normal SIOCOUTQ, SIOCOUTQNSD was never handled in compat
mode. Add it to the common socket compat handler along with similar
ones.

Fixes: 2f4e1b397097 ("tcp: ioctl type SIOCOUTQNSD returns amount of data not sent")
