Merge branch 'strparser-Fix-lockdep-issue'
Tom Herbert says:
====================
strparser: Fix lockdep issue
When sock_owned_by_user returns true in strparser. Fix is to add and
call sock_owned_by_user_nocheck since the check for owned by user is
not an error condition in this case.
====================
Fixes: 43a0c6751a322847 ("strparser: Stream parser for messages")
