af_unix: read UNIX_DIAG_VFS data under unix_state_lock

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

af_unix: read UNIX_DIAG_VFS data under unix_state_lock

Exact UNIX diag lookups hold a reference to the socket, but not to
u->path. Meanwhile, unix_release_sock() clears u->path under
unix_state_lock() and drops the path reference after unlocking.

Read the inode and device numbers for UNIX_DIAG_VFS while holding
unix_state_lock(), then emit the netlink attribute after dropping the
lock.

This keeps the VFS data stable while the reply is being built.
