mainline inclusion from mainline-v5.5-rc1 commit 9d7bf41fafa5b5ddd4c13eb39446b0045f0a8167 category: bugfix bugzilla: 26804 CVE: NA

-------------------------------------

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