AF_UNIX: Second socket created with socketpair fails with ENOTCONN upon getpeername

Description

When creating a socket pair using the POSIX "socketpair" call, it is assumed that both sockets are interconnected.

To check that they are indeed connected, and connected with each other, one can compare the addresses returned by getsockname and getpeername respectively.

However, as of hrev57177, calling getpeername on the second socket in the AF_UNIX domain returns ENOTCONN ("Socket is not connected"). It works fine for AF_INET.

This is critical for code that checks for the correct connection state (regardless of the actual address, for what it's worth).

Upon further investigation, it looks like getpeername is also broken for other AF_UNIX sockets (not just those created via socketpair).
