CVE-2025-38462

In the Linux kernel, the following vulnerability has been resolved:

vsock: Fix transport_{g2h,h2g} TOCTOU

vsock_find_cid() and vsock_dev_do_ioctl() may race with module unload.
transport_{g2h,h2g} may become NULL after the NULL check.

Introduce vsock_transport_local_cid() to protect from a potential
null-ptr-deref.
