Alexander Mikhalitsyn 8f851a75bb scm: fix MSG_CTRUNC setting condition for SO_PASSSEC
[ Upstream commit a02d83f9947d8f71904eda4de046630c3eb6802c ]

Currently, kernel would set MSG_CTRUNC flag if msg_control buffer
wasn't provided and SO_PASSCRED was set or if there was pending SCM_RIGHTS.

For some reason we have no corresponding check for SO_PASSSEC.

In the recvmsg(2) doc we have:
       MSG_CTRUNC
              indicates that some control data was discarded due to lack
              of space in the buffer for ancillary data.

So, we need to set MSG_CTRUNC flag for all types of SCM.

This change can break applications those don't check MSG_CTRUNC flag.
