Replace direct socket family comparison with the standard
VIR_SOCKET_ADDR_IS_FAMILY() macro for consistency.

The codebase uses VIR_SOCKET_ADDR_IS_FAMILY() as the standard way
to check socket address families. This patch updates one remaining
instance that was using direct field access
(addr->data.sa.sa_family == AF_UNIX) to use the macro instead.

This improves code consistency and makes the code more maintainable
by centralizing the family checking logic.
