CVE-2026-45887

In the Linux kernel, the following vulnerability has been resolved: af_unix: Fix memleak of newsk in unix_stream_connect(). When prepare_peercred() fails in unix_stream_connect(), unix_release_sock() is not called for newsk, and the memory is leaked. Let's move prepare_peercred() before unix_create1().
